Check These Before You Inquire
01
Start with roof type
Metal / tile / flat decides penetration rules and whether you need hooks, L-feet or seam clamps.
02
Match clamp to frame
Mid clamps share frames; end clamps finish edges — thickness must fit the rail channel.
03
Finish follows site
Coastal or humid sites prefer HDG or stainless — name the standard in the inquiry.
04
Send a complete brief
Drawing or part no., material, finish, qty and lead time speed up the quote.
