Our rail clamps are machined to fit your rail perfectly, leaving a gap of .030 between the clamp half and keeper half. Our clamps hold on the rail in any kind of weather. We use 60/61 T-6 aluminum anodized to protect against the harsh elements out there, but best of all we make clamps for all the sizes out there. Standard is from 1/2" up to 1-1/2", specify sizing when ordering.
