Product Questions & Answers

trying to clamp 1-1/2 inch pipe, is the 48.3 mm size the right one or am i off a bit?

Question by: Billy S on Jun 11, 2025, 2:10 PM

For a 1.50 inch pipe size, the clamp size listed as 48.3 mm matches up. The note on the product gives the conversion too, mm size x 0.03937 = inch size, which puts 48.3 mm right around 1.90 inches for the outside diameter sizing.

Can you rail mount these clamps, or is it just weld plate only?

Question by: Curt R on Dec 31, 2025, 1:22 PM

Rail mounting is indeed an option for group sizes 3s through 6s. The weld plate style is also available for single clamps.

what's the recommended clamp spacing for 1-1/2 inch pipe with one of these?

Question by: Lee H on Oct 18, 2025, 1:41 PM

For 1-1/2 inch pipe, the recommended support spacing is 9 feet between clamps. If you're working with 1-1/2 inch tubing instead of pipe, that drops to 7 feet. Worth knowing the difference since the spacing tables are separate for pipe versus tubing on this product.
