How many test plugs have you lost down an inspection opening?
Made of zinc-plated steel, this adaptor has a 200mm handle to tighten the test plug from outside the pipe and prevents losing the plug down the pipe. Keeps hands clear of the inside of the pipe and saves knuckles and wrists from cuts and abrasions. Includes a 6 inch pressed steel test plug.. Screw and wedge mechanism grips twice as tight as standard hand tightening.
