TS-72R

72-Tooth Quick Ratchet

5° swing arc. Fits where knuckles can’t.

1/4" and 3/8" drive quick ratchets with 72 teeth — a 5° swing arc for engine bays and dash frames where a quarter turn is all the room there is. Push-button quick release holds sockets until you decide otherwise.

Heat-treated CR-V at the middle of the DIN hardness band: hard enough to hold, soft enough not to shatter. Every batch torque-tested past the standard’s limit.

Questions buyers ask about this tool

The questions importers, distributors and tool programs send us — answered here, and answered live by the online assistant in the corner of this page.

Sealed head or serviceable?
Serviceable — the cover plate comes off for cleaning and re-greasing, which doubles the service life in dirty trades. Sealed-head variant on request.
Do you publish torque-to-failure data?
Yes, per batch. The catalog lists proof torque; importers can request the failure-test series behind it.
Can the handle carry our logo?
Yes — laser-etched or molded-in. Private-label artwork guide is in the downloads section.
