Orfitrans® Stiff

The Gold Standard

Orfitrans Stiff is everything you want and need in a check socket material.

This very rigid transparent material will not break, crack or shatter when dropped. It is virtually indestructible, but you can still easily drill into Orfitrans Stiff. You will love the way it pulls (easily and uniformly) and the material feels great.

No other material comes close to Orfitrans Stiff in performance and quality. Once you start to use Orfitrans Stiff you will immediately know why it is the “GOLD STANDARD”. If you are having difficulties with socket material that is too brittle and cracks or shatters when dropped, Orfitrans Stiff is what you need.

It is available in thicknesses of 8 mm, 10 mm, 12 mm and 15 mm.
