1/4" Thick 5.75" x 4.375" D-Pipe Aluminum Grommet Pad | Right Hand | D3 Profile | Marine Grade 6061-T6
00154-R
Right-Hand Grommet Pad for D3 D-Profile Pipe
1/4" (0.250") thick marine-grade 6061-T6 aluminum grommet pad designed to wrap around D3 D-profile pipe. Through-holes with grommet inserts provide galvanic isolation between stainless hardware and the aluminum substrate while distributing fastener loads over a wider surface area to prevent deck damage. The 5.75" x 4.375" rectangular profile with a 3" × 1.875" D-cutout contour matches D3 pipe geometry. Right-hand orientation — pair with SKU 00154-L for symmetrical port/starboard installations.

Frequently Asked Questions
What does a grommet pad do?
A grommet pad wraps around D-profile pipe with 3 through-holes Ø 3/8" that accept grommet inserts. The inserts provide galvanic isolation between stainless steel hardware and the aluminum deck substrate while distributing fastener loads to prevent cracking or damage to the fiberglass.
What does "Right Hand" mean?
Right-hand orientation means this pad mirrors the left-hand version (SKU 00154-L). Pair both for symmetrical port/starboard installations on T-tops and towers.
What does D3 mean?
D3 refers to the D-profile pipe size this pad matches — a 3" wide D-shaped aluminum profile commonly used in T-top and tower construction.
How is this different from an internal mounting pad?
An internal mounting pad welds inside the pipe with tapped holes for invisible fastener installation. This grommet pad mounts on the outside of the pipe with through-holes and grommet inserts, providing galvanic isolation and external fastener access.
