Oil-finished, solid teak porthole mirror frame with brass studs. Constructed of high-quality, kiln dried, fully-aged teak straight from the forests of Thailand, each Whitecap Teak product features a naturally high oil content for incredible durability over decades. Resists warping, rotting, and damage from insects and withstands extreme weather conditions such as salt, sun, snow, and rain. Intricate grain patterns and color variations make each unique piece as beautiful to your eyes as it is to the touch. Whitecap Teak Teak can be left out in the weather all year long with a proper application of teak oil/sealer annually to maintain its golden color. Matures to a silver gray without applied seal, but can be restored with a good teak cleaner and one or two liberal applications of high-quality teak oil. Cleans up easily with soap and water-avoid chemical cleaners. Traditional assembly techniques-dove-tail and mortice, tenon joints, countersunk screw fittings-and waterproof adhesive ensure strength and durability. Sanded and hand-finished to a rich, elegant luster. Diameter: 10-1/2.
