QUESTIONS & ANSWERS

Have a Question?

Ask a Question

I'd like to reconfirm the diameter of holes. Is it exactly 0.25 inches? Are 1/4‑20 UNC bolts unsuitable for them?

Yes, we recommend using **1/4"-20 stainless steel screws/bolts** for those holes. They are suitable for this application and should provide a secure fit.
What is the size of the 4 mounting holes in a RAM-B-202U-152?

The four hole pattern is 1" x 1.5" and the holes themselves are .25" in diameter.
Is the hole pattern considered to be 4 hole AMPS?

No, the hole pattern in the RAM-B-202U-152 is 1" by 1.5", the RAM-B-347U does have a 4-hole AMPS pattern however.
