The 50026858 Trivac Leaf Collection Bag from ZHIXING is engineered as an aftermarket solution matching replacement part numbers 50015035 and 50026858. This bag is designed to interface with a wide range of Worx leaf vacuum configurations, including WG502, WG508, WG505, WG509, WG500, WG501, and WG518. It utilizes a twist-to-fix mechanical interface where the user aligns the connector collar with the blower port and rotates it into a locked position. The listing details package dimensions of 5.04 x 4.84 x 3.43 inches with an overall weight of 1 pound, making it a compact yet robust accessory.

Fabric construction on this bag stands out due to an 80% cotton and 20% polyester material blend. This specific ratio provides a balance between structural strength and fine-particulate filtration, preventing mulched debris from blowing through the textile wall while maintaining air discharge. It holds up to 10 gallons of mulched leaves, minimizing trips to the disposal bin during heavy yard work. The zipper installation features reinforced sewing thread around the perimeter to prevent separation under the mechanical strain of dense, damp yard debris.

Carrying ergonomics are addressed through an integrated shoulder strap equipped with a buckle adjustment system. Users can adjust the strap length to balance the weight of the collection sack against the blower housing during long cleanups. While this bag provides wide compatibility across early WG-series blowers, it relies on the traditional twist interface and will not mount to newer Trivac blowers lacking the rotational latch tabs.

• Compatible with Worx part numbers 50015035 and 50026858 across WG500 through WG518 series
• Fabric construction composed of 80% cotton and 20% polyester weave
• Maximum storage volume holding up to 10 gallons of mulched leaves
• Adjustable shoulder strap with integrated buckle hardware

Best for: WG505 and WG509 factory replacement seekers

Pros

• Direct OEM factory fitment
• Tool-free slide-and-twist attachment
• Full-length emptying zipper
• Factory-matched 10-gallon volume

Cons

• No manufacturer accessory warranty

The WORX Trivac Leaf Collection bag, carrying part number WGBAG500 and model number 50026858, represents the original equipment manufacturer replacement produced directly by WORX. Designed specifically for the WG505, WG505.2, and WG509 series blowers and vacuums, this OEM bag ensures direct factory tolerance matching. It features a tool-free slide-and-twist attachment collar that mates with the housing locks without requiring aftermarket adapters. The listing specifies that this accessory bag does not carry an individual warranty.

Capacity is rated at 10 gallons of mulched debris, which aligns with the reduction ratios generated by the metal impellers on compatible WG-series units. Emptying the bag is managed by a full-length zipper running along the lower seam, allowing users to dump compacted leaf matter directly into yard waste containers without shaking debris through a narrow neck. Yard maintenance teams comparing tool systems often note that dedicated corded units produce sustained suction similar to running a commercial dewalt leaf blower, making a dependable collection sack critical for extended collection cycles.

Because this is a genuine OEM worx wg505 replacement bag and worx wg509 collection bag, the collar tabs correspond precisely to the original factory specifications. This eliminates fitment play or collar slipping during operation. However, its compatibility scope is strictly limited to the WG505, WG505.2, and WG509 families, meaning owners of other series units must verify their port tabs before selecting this model.

• Official WORX replacement component under model number 50026858 and WGBAG500
• Direct slide-and-twist toolless locking collar for WG505, WG505.2, and WG509
• Full-length heavy-duty zipper for rapid clearing of collected mulch
• Ten-gallon collection capacity matching factory equipment specifications

Best for: Budget-focused WG500 series replacement owners

Pros

• Reinforced zipper perimeter stitching
• Standard 10-gallon mulch capacity
• Adjustable buckle shoulder strap

Cons

• Rigid plastic collar construction

The 50026858 WGBAG500 Trivac Leaf Collection Bag by KBZ is built as an alternative replacement for part numbers 50026858 across the WG502, WG508, WG505, WG509, WG500, and WG501 lineup. The listing highlights a durable construction pairing a cotton textile body with a molded plastic attachment collar. With dimensions measured at 5 x 4.9 x 5 inches and a black finish, this unit is engineered to capture 10 gallons of mulched material during routine vacuuming.

A primary point of mechanical failure on leaf vacuum bags is the zipper track pulling away from the fabric under load. KBZ addresses this by reinforcing the sewing thread along the entire zipper zone, securing the closure mechanism against outward pressure caused by compacted leaves. Emptying the contents is handled through this zippered access, allowing operators to quickly dump debris and return to clearing lawn areas.

Installation follows the standard twist-lock procedure: the plastic collar slides into the blower vacuum interface and rotates until the locking tabs seat properly. An adjustable buckle shoulder strap allows the user to tailor the carry height based on individual stature. While providing reliable functionality across legacy tools, the listing specifies compatibility exclusively for vacuum cleaner applications within the listed WG500-WG509 series.

• Engineered to replace 50026858 for WG500, WG501, WG502, WG505, WG508, and WG509
• Constructed from cotton fabric with a molded rigid plastic connector
• Reinforced sewing thread along the zipper track to prevent seam tear-out
• Adjustable shoulder strap utilizing a quick-adjust buckle mechanism

Best for: Operators wanting fast clip-in collar attachment

Pros

• Quick-release clip eliminates twisting
• Heavy-duty cotton and canvas fabric
• Cross-compatible with Hyper Tough models
• Reinforced high-stress point stitching

Cons

• Incompatible with WG512 blowers

The 50026858 WGBAG500 Leaf Collection Bag from Viefow provides an upgraded mechanical design for operators tired of traditional twist-lock collars. While engineered for the Worx WG500, WG501, WG502, WG505, WG508, and WG509 series, this bag also extends compatibility to Hyper Tough electric blower mulcher models HT10-401-002-04 and HT10-401-002-05. Weighing 0.43 kg, the unit replaces part numbers 50015035 and 50026858 while retaining the standard 10-gallon mulch volume.

The standout feature of this Viefow model is its upgraded clip-in attachment collar mechanism. Instead of requiring operators to push and rotate the collar into place, this design utilizes a quick-release locking system that clips directly onto the blower port. This eliminates alignment struggles and prevents collar jamming caused by fine grit entering the twist channels. Operators handling intensive debris clearing alongside tools like a dewalt battery leaf blower 60v will appreciate how rapidly this clip-in system connects and disconnects during dump runs.

Durability is reinforced through a cotton and canvas textile construction. High-stress points receive extra stitching to withstand the weight of damp mulched leaves. The heavy-duty zipper is reinforced with perimeter stitching to ensure smooth sliding without catching or separating under heavy yard cleaning duty cycles.

• Upgraded quick-release clip-in collar eliminating standard rotational twisting
• Cross-compatible with Worx WG500-WG509 series and select Hyper Tough models
• Heavy-duty cotton and canvas fabric build weighing 0.43 kg
• Reinforced structural stitching around high-stress zipper zones

The 50026858 Trivac Leaf Collection Bag WGBAG500 manufactured by LIZEWEI serves as an alternative replacement for Worx part numbers 50015035 and 50026858. It is engineered to fit Worx blower vacuum models WG500, WG501, WG502, WG505, WG508, and WG509. The listing specifies an item weight of 0.44 kg and a depth of 5.5 inches, presenting a functional replacement sack for residential fall lawn maintenance.

Diverging from traditional canvas weaves, this LIZEWEI model utilizes microfiber textile material. Microfiber delivers tight particulate filtration, capturing fine dust that often escapes coarser cotton weaves while maintaining sufficient porosity for continuous blower exhaust. The 10-gallon mulch capacity accommodates significant yard volume, cutting down the total number of collection cycles required to clear a lawn.

Debris evacuation is handled by a full-length zipper located across the bottom of the bag. Reinforced sewing thread lines the zipper assembly to ensure structural integrity when dumping packed mulch. The bag attaches using the classic rotational collar system that locks into the blower outlet, though the listing does not specify whether an adjustable shoulder strap is included in the package.

• Direct alternative for part numbers 50015035 and 50026858
• Constructed from microfiber material for enhanced particulate filtration
• Full-length bottom zipper configuration for rapid leaf evacuation
• Ten-gallon capacity holding dense mulched yard waste

The Leaf Vacuum Blower Storage Bag produced by FUSNCNZ represents a departure from the rigid collar bags in this lineup. Specifically tailored for the WORX WG512 TRIVAC 2.0 vacuum blower, this bag addresses the unique discharge architecture of newer Trivac machines. It carries model number FUSNCNZ-19050890 and has a listed product weight of 2.2 pounds, providing a soft-sided collection body for dry leaves and light garden debris.

Rather than using a molded twist-lock or clip-in plastic collar, this bag employs an adjustable drawstring inlet featuring a cord and locking toggle. Operators slip the opening over the WG512 discharge port and cinch the toggle tight against the machine tube. This flexible opening accommodates the circular geometry of the Trivac 2.0, providing a secure friction fit without requiring rigid plastic tabs. Groundskeepers managing secondary blowing tasks with compact gear such as a dewalt blower 20v max can appreciate the compact storage footprint of this soft-sided unit.

A wide zippered opening allows users to release mulch into disposal bags without struggling through the narrow intake collar. The flexible fabric construction expands as mulched leaves enter the chamber and folds completely flat when empty, making it simple to stash in a garden shed or equipment cabinet. The listing does not specify a numerical gallon capacity, but emphasizes seasonal dry leaf and debris handling.

• Engineered specifically for compatibility with the WORX WG512 TRIVAC 2.0
• Adjustable drawstring inlet with cord-locking toggle for custom port cinching
• Wide zipper opening across lower section for streamlined debris dumping
• Foldable soft-sided fabric construction weighing 2.2 pounds
