Kerlista pole saw attachment & extension pole for square-shaft trimmers — Black, 3/8" chain ready, fits Husqvarna/Stihl/Ryobi

The Kerlista pole saw attachment and extension pole convert compatible string trimmers and powerheads into a lightweight, reach-ready pruning saw for branches and limbs.

This two-piece kit includes a chainsaw-style head and a matching extension pole engineered to work with many popular trimmer powerheads that use a square shaft and 1" tube. Designed for homeowners and pros who need extra reach without buying a full pole saw, the unit accepts a 3/8" chain and fits a long list of models from Husqvarna, Stihl, Ryobi, Greenworks and other brands. Before buying, verify your tool’s shaft size and mounting pattern to ensure compatibility.

Which trimmers and powerheads will this Kerlista pole saw fit?

The attachment was built to match a wide range of consumer and commercial trimmer powerheads that share a common square drive and 1" outer tube. It fits many Husqvarna and Stihl garden tools plus models from Ryobi, Greenworks, Poulan, Murray, Toro and more. Check your tool model against the included compatibility examples and confirm shaft dimensions before ordering.

• Common Husqvarna models: many 128/125-series kits and select 322/327 series heads
• Works with several Stihl combi-system and motor units listed by model number
• Includes examples for Ryobi, Greenworks, Poulan, Murray, Toro and other popular brands
• Requires square shaft and 1" tube — verify your powerhead type

How easy is it to install and swap between tools?

Installation is straightforward: slide the adapter onto the trimmer’s square shaft, secure with the existing locking mechanism, and attach the extension pole to reach higher branches. No permanent modification of your base tool is required, so you can return to string trimming quickly. Basic hand tools may be helpful for final tightening.

• Simple slide-on fit for compatible square-shaft powerheads
• No special adapters or welding — uses existing locking fasteners
• Extension pole nests into the attachment for compact storage
• Chain is 3/8" pitch (90X) for common replacement options

What are the cutting specifications and maintenance tips?

The saw accepts a 3/8" chain in the 0.043–0.045" gauge range (90X), a common size that makes re-tensioning and replacement easy. Keep the chain sharp and correctly tensioned, use bar oil during operation, and inspect mounting hardware regularly for safe performance. Follow standard chainsaw chain care to preserve cutting quality and extend component life.

• Chain type: 3/8" pitch, 0.043–0.045" gauge (90X)
• Use bar oil and check chain tension before each use
• Inspect attachment points and shaft engagement for wear
• Replace chain and bar with compatible aftermarket parts as needed

How long is the extension and how does it change reach?

The included extension pole increases working reach so you can prune higher limbs while remaining on the ground. Exact reach depends on your base tool and how you handle the setup, but the pole adds several feet of clearance versus a handheld saw. Use a stable stance and, when needed, a ladder for very high branches while following safe cutting practices.

• Extension pole designed to add multiple feet of vertical reach
• Allows ground-level pruning of higher branches without climbing
• Compact for transport when detached from the powerhead
• Recommended: test balance and handling before full-speed cutting

Who this is for: The Kerlista pole saw & extension kit is ideal for homeowners, landscapers, and property managers who already own a compatible trimmer or multi-tool and want a cost-effective way to add pruning capability. It’s best for users who can verify shaft compatibility, handle a chainsaw-style cutting head safely, and perform routine chain maintenance. If you need a dedicated professional pole saw with integrated power, consider factory-made pole saw units, but if versatility and value are priorities, this attachment lets you expand the usefulness of an existing trimmer system.
