Overview
The Channellock CHL430 is a 10 inch straight jaw tongue and groove plier forged from high carbon US steel, sized for plumbing, automotive and household repair work where a firm grip on pipes, nuts and bolts is the main job.
- 10 inch straight jaw tongue and groove design
- Permalock fastener joint in place of a nut and bolt
- Forged high carbon US steel with rust resistant coating
- Ergonomic blue non-slip grip handles
Who it's for
Plumbers, mechanics and homeowners who regularly grip pipes, fittings or oversized nuts will get the most from the 10 inch reach and adjustable jaw. Buyers who only need a small pocket plier for light tasks may find this size more plier than they need, even though several owners still carry it daily.
Pros and cons
- Permalock joint avoids the nut and bolt failure of cheaper pliers
- Laser hardened teeth grip worn or rounded fasteners
- Comfortable enough for users with reduced hand strength
- Handles pipe, automotive and general repair tasks
- One long time buyer felt the current build is thinner than older Channellock pliers
- Country of manufacture questioned by at least one reviewer despite the US steel claim
Performance notes
The tongue and groove channel lets the jaw slide into multiple width settings so one tool grips small nuts and large pipe fittings alike. The Permalock fastener pins the joint instead of using a nut and bolt, which is the failure point Channellock is targeting on cheaper pliers. Laser hardened, 90 degree teeth bite into rounded or worn fasteners rather than slipping.
