Pull action latch clamps are used for repetitive opening & closing of doors or lids during moulding, latching and assembly operations. They feature a handle to place & press down a clamping pull bar or hook around the opposing latch attached to a workpiece. These clamps offer a powerful closing force for positive holding of the workpiece and a thumb control lever for convenient single handed operation. They are generally available in fixed latch, U-hook (horizontal and vertical) and J-hook type designs. Destaco 331 Series clampsare mounted parallel to the latch surface for pulling workpieces. Destaco 331 clamp has a flanged base for installation on flat, horizontal surfaces. This horizontal U-hook style latch clamp has steel construction for strength and resistance against wear & tear due to abrasive conditions. Raptor Supplies offers these 331 Series clamps in variants having stainless steel construction for corrosion resistance; Toggle Lock Plus mechanism for acting as a secondary locking feature in the clamp. 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 vertical U-hook, providing a maximum holding capacity of 1000 lb.

Frequently Asked Questions:
Q. What other variants of Destaco 331 latch clamp are available on Raptor Supplies?
A. Raptor Supplies also offers 331-SS latch clamp having stainless steel construction for corrosion resistance. We also supply these similar manual clamps having Destaco Toggle Lock Plus mechanism to prevent accidental opening of the clamps (331-R).
Q. Is Destaco 331 latch clamp available in different hook lengths?
A. Destaco supplies similar latch clamps in different hook lengths of 25 mm longer than standard length (331-M-25), 50 mm longer than standard hook length (331-M-50) and 100 mm longer than standard length (331-M-100).
Q. How do latch clamps work?
A. These pull action latch clamps has 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 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.
