Their simple design and quality steel construction help them meet long range trouble-free service requirements in the harshest environments.","application":"Raised watertight hatches are typically found along the gunnels of a barge as well as on the bow/ stern and on top of cargo compartments or tanks. They are used to access wing tanks, the rake compartment, cargo compartments etc. for venting, filling, and inspecting. Raised watertight hatches that feature a ullage hatch are also commonly used on tank barges where the ullage is used as a vent or an inspection port to measure or verify cargo.","material":["Steel (ASTM A36)","Painted Primer Grey","UMC-464-5 Steel Hatch 4-Dog with 8” Ullage Inspection"],"materials":["steel"],"features":["Tumble Bolt – Bronze","Dog Handle – Steel with Zerk","Bolt 5/8-11 – Zinc Plated Steel","Nut 5/8-11 – Stainless Steel","Gasket – Nitrile Rubber","All of our raised watertight hatches meet ABS (American Bureau of Shipping) requirements for design and materials.","Custom coaming heights available upon request.","Other gasket material available upon request.","Various hardware options available:","– Steel, Stainless Steel, & Bronze Dog Handles (available with or without grease fittings).","– Bronze & Stainless Steel Tumble Bolts.","– Lug Bolts and nuts made from dissimilar metals to prevent galling and corrosion.","Flame screens available upon request (sold separately)."],"certificates":[],"specifications":[[{"Model Number":"UMC-464-5 / 144","Description":"Raised 4 Dog 18×24 Watertight Hatch + 8″ Ullage & Hasp","Part Number":"03800-130J","Clear Opening In.
