The Low Profile Hatch has soft styling and sleek looks, with a user-replaceable lens.Until now, replacing scratched or cracked lenses meant sending the lid to the manufacturer or paying a professional to repair it. Now Lewmar has created a two-piece frame with tough, gray acrylic that can be replaced simply by unscrewing the frame and inserting the new lens. The seal and acrylic are fitted into the aluminum frame to produce a stronger, more leak-proof hatch.CE-certified aluminum frame has smooth, rounded edges, inset hinges and rounded corners for snag-resistance. All hatches feature a vent position, flange base and sizes 30 and larger have lockable internal and external handles for added security. CE Area II approved. All hatches have flange bases.Low-profile hatches have 8mm acrylic in sizes 00 through 54, and 10mm acrylic in size 60.Key FeaturesThe Low Profile Hatch has soft styling and sleek looks, ideal for use on a powerboatSmaller ventilation hatches are suitable for any deck location on sailboats, while the larger sizes can be used as foredeck hatches on smaller to mid size yachtsOutside handles allow the hatch to be opened from on deck if it is not lockedLow profile hatches open up to 180 (round hatches open to 170)Friction levers hold the lid open in any position up to 95Smoked gray acrylic lens, clear-anodized aluminum frame for corrosion resistanceCurved upper frame profile for strength as well as modern stylingDoesnt require deck recess to installIncluded Accessories: None (Trim and Screen Kits available online)Low Profile Hatch Selection ChartHatch SizeCutout Size (L x W)Overall (L x W x H)Corner Radii008 5/16" x 8 5/16"11 1/16" x 11 1/16" x 1"2 7/8"0310 1/16" x 10 1/16"9 11/16"x 11 7/8" x 1"2 7/8"1010 1/4" X 10 1/4"13" x 13" x 1"2 7/8"2012 11/16" x 17 13/16"10 11/16" x 16 7/16" x 1"2 7/8"3012 7/8" x 18"15 5/8" x 20 3/4" x 1"2 7/8"4016 9/16" x 16 9/16"19 5/16" x 19 5/16" x 1"2
