Product Description

Bomar Commercial Grade Series Hatches are rugged, watertight and mean business when it comes to commercial boating. Bomar’s Flush Watertight Series Hatches are commercial grade, built to last out of durable Almag-35 cast aluminum, with stainless steel hardware and t-handle. For nearly three decades Bomar, a division of Pompanette, LLC, has designed and manufactured the finest ports, hatches, windows, and doors for the marine industry. Since the beginning, the Bomar name has been synonymous with innovative design, flawless craftsmanship, and the highest quality materials. You will find that the Commercial Grade Series Watertight Deck Hatches live up to the respected Bomar name.

Bomar uses 535 magnesium hardened aluminum to construct our Commercial Grade Series watertight hatches. The raw almag-35 is heated to 1100 degrees F at the Bomar foundry and is then melted and poured into our proprietary cast molds. The Commercial Grade Series watertight hatches are professionally assembled in-house with 316L, marine grade, stainless steel  T-handle & fasteners.  Stainless steel is ideal for harsh marine environments due to it’s rust & corrosion resistance, strength and luster.
