Special Application Grips
Liners and Retainers
Tension rods in many sizes, designs and materials are maintained in stock. A majority of our tension rods are manufactured for special design requirements.
Many of our customers find our refurbishing process to be an economical alternative to purchasing new fixtures or for developing backup fixtures for emergency situations. This can be very cost effective and expedient to your existing grips. Typically grips that appear to be at the end of their useful service life can be reconditioned and placed back into service for 65% of the original cost.
