3/8" 8" x 5.5" D-Pipe Aluminum Countersunk Pad | Left Hand | Marine Grade 6061-T6
Part Number: 0072-L
Countersunk Mounting Pad for D5 D-Profile Pipe — Left Hand
3/8" thick marine-grade 6061-T6 aluminum countersunk pad engineered for D5 D-profile pipe installations requiring a flush mounting surface in a compact footprint. Countersunk holes allow fasteners to sit flush with the pad surface, providing a clean, low-profile appearance while maintaining structural integrity across the 8" x 5.5" pad area. The contoured profile conforms to D5 pipe curves at any mounting angle. Left-hand orientation — pair with SKU 0072-R for symmetrical port/starboard installations.

Frequently Asked Questions
What does a countersunk pad do?
A countersunk pad features conical holes that allow flat-head fasteners to sit flush with the pad surface, creating a smooth, low-profile appearance. This prevents hardware protrusion that could snag lines, scratch surfaces, or interfere with equipment mounted over the pad.
What does "Left Hand" mean?
Left-hand orientation means this pad mirrors the right-hand version (SKU 0072-R). Pair both for symmetrical port/starboard installations on T-tops and towers.
What does D5 mean?
D5 refers to the D-profile pipe size this pad matches — a 5" wide D-shaped aluminum profile commonly used in heavier T-top and tower construction.
How is this different from the 9.5" x 6.5" D5 countersunk pad?
This pad has a smaller 8" x 5.5" footprint for installations where space is limited but D5 pipe compatibility is still required. The smaller size reduces weight and pad surface area while maintaining the same 3/8" thickness and flush countersunk mounting.
