Channellock’s 16.5-inch plier steps up to handle the large plumbing fittings, pipe unions, and oversized nuts that smaller tools cannot grip. The straight jaw design with laser heat-treated teeth delivers a secure bite on both flat and round surfaces, while the undercut tongue and groove joint prevents jaw slippage between positions when you’re applying maximum load. This is the size that gets reached for when standard tools simply won’t fit.
