Additionally, our comprehensive catalog has been renewed for the first time in six years and is now available for shipping. It covers all catalog products, including new items, and consists of a substantial 1,390 pages. We invite you to visit our booth (East Exhibition Hall, Hall 3, 28-32) to experience the actual operation and feel of our products. *For more details, please feel free to contact us.

This is a flat handle that allows for a two-point lock with the use of a rod. It maintains both the "retracted" and "extended" states of the arm. The rod will not return to the locked position on its own. The handle and arm move in conjunction with each other. The state of the rod can be easily identified by the state of the handle. It is a flush type with minimal protrusion from the mounting surface and is suitable for both left and right use. By using it in conjunction with the THA-433-F (fixed type), it can also be used for double-opening (French doors).

It complies with SEMI standard S8-0218 Section 6.8.1 "Hook grip type handle (4-finger) when wearing cleanroom gloves." By protruding the grip section from the end face, it reduces interference with the inside of the housing while also conforming to SEMI standards. The ample opening and curled grip ensure both safety and usability.

When used together with the stainless steel round bar handle THA-31SUS, the installation looks neat. Made of stainless steel, it has excellent corrosion resistance.
