3/8" 9.5" x 6.5" D-Pipe Aluminum Countersunk Pad | Left Hand | Marine Grade 6061-T6
Part Number: 0070-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. Countersunk holes allow fasteners to sit flush with the pad surface, providing a clean, low-profile appearance while maintaining structural integrity across the 9.5" x 6.5" footprint. The contoured profile conforms to D5 pipe curves at any mounting angle. Left-hand orientation — pair with SKU 0070-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 0070-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 a grommet pad?
A grommet pad uses through-holes with grommet inserts for galvanic isolation between stainless hardware and aluminum. A countersunk pad uses flush countersunk holes for a clean, low-profile appearance where galvanic isolation is not required or is handled separately.
