Frequently Asked Questions

What does "countersunk" mean for this pad?
Countersunk means the mounting holes are chamfered so countersunk head screws sit flush with the pad surface — no protruding screw heads that could snag lines or cause injury.

What fasteners work with this pad?
Use 3/8" countersunk head screws to match the mounting holes. Hardware and fastener requirements vary by installation — consult your fabricator for the appropriate specifications.

Why a rectangular pad instead of round?
Rectangular pads distribute fastener load across a wider surface area and align naturally with flat pedestal and hard top panels where a round pad would waste corner contact area.

In plain terms what this means is that if you want to ship your product to any non-contiguous US territory or internationally, you, the customer, has to provide us with the warehouse address of the carrier that serves your locality with an address within the contiguous 48-US States, as we do not ship overseas on our own.
