Description
Overview:
This chain catcher is a safety component for Husqvarna petrol chainsaws, designed to sit beneath the drive sprocket area and arrest a thrown or derailed chain. It is a genuine Husqvarna part, MPN 503527401 (also referenced as 503 52 74-01), engineered for a precise fit on the Husqvarna 40 and 45, and also used on the 49. Built from a robust metal alloy for impact resistance, it helps protect the operator and the saw body by catching the chain before it can whip back. The compact, bolt-on design uses the existing mounting point on the saw chassis for reliable location. Suitable for professional and domestic users, it supports safe, consistent operation during felling, cross-cutting, pruning, and firewood processing.

Typical Applications:
Used whenever the saw is operated, including forestry work, landscaping, fencing, storm clean-up, and general property maintenance.

Helps maintain a safe setup for tasks such as felling, bucking, snedding, pruning, and cutting firewood, whether on-site or at home.
