  More About Our Materials

The T-Top Extender Mounts are manufactured from solid 6063-T6 Aluminum Bar Stock. Machined to exact tolerances and Clear Anodize coated to prevent oxidation.

6000 Series Aluminum: Alloys in this group contain silicon and magnesium in approximate proportions
to form magnesium silicide, thus making them capable of being heat-treated.
The major alloy in this series is 6063, one of the most versatile of the heat-treatable alloys.
The magnesium-silicon (or magnesium-silicide) alloys possess good formability and corrosion
resistance, with high strength.

The included hardware and fasteners are manufactured from 316 Stainless Steel Which is highly resistant to corrosion.

However, if exposed to salt spray use a corrosion inhibitor such as WD-40, Lanocote or another marine corrosion prevention product between the screws and the mount or take the hardware off of your boat and store. Wash the hardware down with fresh water after each use if exposed to salt spray and coat with a corrosion inhibitor such as WD-40, Lanocote, or other product suitable for preventing metal corrosion in a marine environment.

Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

Moving parts are manufactured from Delrin or Glass Filled Nylon for smooth functions.

The T-Top Extender uses a special marine grade stretch fabric that assures an exact and customized fit for your t-top.
