WK Model WTH-R

Raised Watertight Hatch

Round, square, rectangular, hatch within a hatch Рanything is possible for our engineers!   When the location does not require a flush hatch, raised hatches are often used as they are easier to  install and are often more cost effective. Operation can be from one or both sides utilizing rotating dogs, or from the top only when drop-bolts are used.  Options include spring balancing, power operation, hold open braces, and panic bar operation.
