TRI Square Top Jaws

Tri square top jaws are adjustable hard top jaws used on three jaw chucks to clamp a range of square sections. 

This simple but clever top jaw system removes the need in many instances to use 2 or 4 jaw chucks for the clamping of square section. 

Tri square top jaws are ideal for clamping a series of square parts of different size because of the quick and easy adjustment from one size to another. 

Tri square top jaws allow more universal use of three jaw chucks allowing the clamping of square and round section – when using chucks as fixtures horizontally on machining centers this can save costs on special fixtures.
