Pull action latch clamps are horizontal or vertical holding type devices that provide a strong closing force to repetitively close & open doors and lids for latching, moulding and assembly operations. They have handles to place the clamping pull bars or hooks around the opposing latches and press down to lock the clamp. These clamps offer a powerful closing force, providing a positive holding and convenient single-handed operation due to thumb control lever in the clamps. It is generally available in 3 major styles, namely: fixed latch type, U-hook type (horizontal and vertical) and J-hook type. Destaco 331-SS pull action latch clamp is mounted parallel to the latch surface for pulling workpieces. This horizontal U-Hook style latch clamp is made up of stainless steel for providing corrosion resistance under harsh environments and minimising damage / wear due to abrasive conditions. Destaco 331 Series clampsare also available in variants having steel construction, Destaco Toggle Lock Plus mechanism and many more. 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-SS pull action latch clamp come in other variants with similar specifications?
A. Destaco supplies similar latch clamps in steel construction for structural rigidity (331) and with Destaco Toggle Lock Plus feature to prevent accidental disconnection of the clamps (331-RSS).
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-SS-M-25), 50 mm longer than standard length (331-SS-M-50) and 100 mm longer than standard hook length (331-SS-M-100).
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; 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 to hold the work items.
Q. How to select the right type of latch clamp?
A. Destaco clamps have steel and stainless steel construction with flange base mounting for easy installation. They are equipped with a U-hook or J-hook for pulling the workpieces using latch plates or other accessories. These clamps come listed with varying holding capacities. They indicate the maximum external force that a clamp in a locked position can resist safely without getting deformed permanently. The customer should also choose clamps on the basis of distance between clamping plate and workpiece in its farthest position.
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 the 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 extra level of safety for the user and the workpiece. Raptor Supplies can deliver Destaco 331-RSS straight line action clamp with Toggle Lock Plus feature and similar specification as Destaco 331-SS manual clamp.
