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.
FEATURES UNIQUE to the NEENAH R-3498 SERIES
- Lid mounted springs move out of the free open area, exposing the free opening.
- Spring position allows more spring rotation, thus more spring power.
- Slam-latch enables opening and closing with ease. Simply pop the lid open and slam it shut.
- Self-contained frame, lid and spring assembly pushes on itself, not external wall structures.
- Easy spring removal and replacement
- Neenah’s Perma-Grip non-skid surface.
Optional threaded hole in frame for Grounding Strap – specify if required.
