Castings strong enough to handle severe loads are inherently heavy. Lifting these heavy lids/gates to gain access to sub-ground utilities has been an issue for maintenance crews. Lifting these heavy covers requires multiple personnel and lifting equipment. With Neenah’s Spring-Assist Hatches, a single maintenance worker can quickly open the lid, and secure it in the upright position with Neenah’s hold open device and perform the necessary work.


Optional threaded hole in frame for Grounding Strap – specify if required.
