Pull action latch clamps feature a handle to place & press down the clamping pull bar or hook around the opposing latch and provide a strong closing force to repetitively close & open doors and lids for latching, moulding and assembly operations. These clamps offer a powerful closing force for positive holding and thumb control lever for convenient single handed operation. These clamps are generally available in 3 major styles that are fixed latch, U-hook (horizontal and vertical) and J-hook type clamps. Destaco 331 Series clampsare mounted parallel to the latch surface for pulling workpieces. Destaco 331-RSS clamp is integrated with Toogle Lock Plus mechanism to prevent accidental disconnection of the clamp. This horizontal U-Hook style latch clamp has stainless steel construction for providing corrosion resistance under harsh environments and minimising damage / wear due to abrasive conditions. Raptor Supplies offers these 331 Series clamps in variants having steel construction for structural strength. It is also offered in variants without Toggle Lock Plus mechanism for reducing operating costs. You can order these latch clamps with longer hooks (25, 50 & 100 mm), by simply adding -M-25, -M-50 or -M-100 at the end of the model number.
We also offer Destaco 334 Seriespull action latch clamps having a vertical U-hook, providing a maximum holding capacity of 1000 lb.

Frequently Asked Questions:
Q. Does Destaco 331-RSS pull action latch clamp come in other variants with similar specifications?
A. Destaco supplies similar latch clamps having steel construction for structural rigidity (331-R). This clamp is also offered in variants without Destaco Toggle Lock Plus feature to reduce the operating costs of the clamps (331-SS).
Q. Does Destaco offer manual clamps with longer hooks than Destaco 331-RSS pull action latch clamp?
A. On request, Destaco can supply similar latch clamps with different hook lengths of 25 mm longer than standard length (331-RSS-M-25), 50 mm longer than standard length (331-RSS-M-50) and 100 mm longer than standard hook length (331-RSS-M-100).
Q. How do latch clamps work?
A. These pull action latch clamps has 3 main components including 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. 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.
Q. Which grease is recommended to be used with Destaco clamps when rebuilding?
A. Whenever you're dealing with the brand's mechanical clamps, it is recommended to use a coupling grease like Mobil XTC.
Q. What does holding capacity mean in terms of clamps?
A. The holding capacity or the holding force depicts the clamp's capability to hold down equipment or sheet metal on the assembly line or during similar manufacturing processes.
