Low Profile Accessories: Trimkits & Screens

Low Profile Accessories: Trimkits & Screens

Trimkits provide an easy and stylish way of finishing a hatch installation inside the cabin. The trimkits come complete with a flyscreen to prevent mosquitoes entering the boat. The trim can be cut to length allowing the trimkit to suit a wide range of deck thicknesses. Trimkits can only be fit to boats with headliners.

Use of trimkits changes the cutout required for the hatch. Add 4mm to Cutout Length "X1" and Cutout Width "Y1", and add 2mm to Cutout Radius "R1". Low Profile Hatches require a minimum Hull Thickness of 15mm and a Maximum Hull Thickness of 62mm.
