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.
