SPARROWS' ADAMS RITE BYPASS DRIVER -- NO locksmith should be without this!
The proliferation of Adams Rite lock hardware in the U.S. is astounding, as it is still the most commonly encountered brand in commercial applications, almost exclusively employed as the hardware of choice for glass doors. It is therefor a no-brainer that a well equipped locksmith will endeavor to have at his/her disposal a wide variety of service tools that can be brought to bear. This deceptively simple tool from Sparrows should be one of those tools.
As with all bypass tools, this one works by acting directly upon the latch mechanism within the Adams Rite housing. The technician threads the tool through the keyway of the mortise cylinder, bypassing the tumblers altogether, and then withdrawing the latch -- effectively acting in the same way the tailpiece or cam of the lock cylinder would.
The tool itself is made of polished steel components and features a permanent thermo plastic handle. Easy to learn and easy to afford.
