Pull action latch clamps provide a strong closing force to repetitively close & open doors and lids in latching, moulding and assembly operations. They feature handles to move the clamping pull bars or hooks around the opposing latches and press down to lock the clamp. These clamps offer a powerful closing force and provide a convenient single-handed operation due to thumb control lever present in the clamps. It is available in fixed latch, U-hook (horizontal and vertical) and J-hook types. Destaco 331-R pull action latch clamp is integrated with a horizontal U-hook to mount parallel to the latch surface for pulling workpieces. This latch clamp is made up of steel, providing structural rigidity in heavy-duty operations, thereby minimising damage / wear due to abrasive conditions. It features Destaco Toggle Lock Plus for increased user safety and maintaining over-centre locking conditions. This Toggle Lock Plus mechanism also prevents the clamp from being accidentally or unintentionally opened. Destaco 331 Series clampsare also offered in stainless steel construction, without Destaco Toggle Lock Plus mechanism and many more variants. You can also order these latch clamps with the longer hooks (25, 50 & 100 mm) by simply adding -M-25, -M-50 or -M-100 at the end of the model number.

Frequently Asked Questions:
Q. Does Destaco 331-R pull action latch clamp comes in other variants with similar specifications?
A. Destaco supplies similar latch clamps in stainless steel construction for corrosion resistance (331-RSS) and without Destaco Toggle Lock Plus (331) for reducing operating costs where this secondary lock mechanism is not required.
Q. Does Destaco offer manual clamps with longer hooks than Destaco 331-SS pull action latch clamp?
A. Destaco can supply similar latch clamps with different hook lengths upon request: 25 mm longer than standard length (331-R-M-25), 50 mm longer than standard length (331-R-M-50) and 100 mm longer than standard hook length (331-R-M-100).
Q. What are the benefits of using Toggle Lock Plus mechanism in Destaco manual clamps?
A. Many of the Destaco manual clamps come with the Toggle Lock Plus feature to act as a secondary locking mechanism and ensure over-centre toggle lock condition of the clamps. This mechanism is essential when fixtures of the clamp are in motion, in a vibratory environment or are inverted. It offers an enhanced level of safety for the user and the workpiece.
Q. How do latch clamps work?
A. These pull action latch clamps has 3 main components - a handle to operate the tool, a clamping arm to act as a contact point between the work item & the clamp and a base to attach the clamp to the surface. Once the simple linkage system of the clamp is put in the over-centre position, the handle is moved for creating a force parallel to the base for holding the work items.
