Anchor sizes:
The bases of our supports are supplied in a size determined by the size of the pipe they are supporting. Here is the breakdown:
For 2.5" & 3" Pipe, the support will have a 8.5" square base plate with 9/16" holes.
For 4" to 12" Pipe, the support will have a 12" square base plate with 13/16" holes.
For 14" to 16" Pipe, the support will have a 13.5" square base plate with 15/16" holes.
For 18" to 24" Pipe, the support will have a 18" square base plate with 1 1/8" holes.
Always refer to your projects plans and local specs for information regarding which size and type of anchors to use to properly anchor the support.
