The heavy duty hinged drainage grate has been designed for ergonomics and ease of access, while providing a higher level of security than a stand-alone frame and grate. The integrated EON LOCK® bolt helps limit unauthorized access and theft. One bolt (instead of four) means easier access for workers.

The optimized ergonomic design substantially reduces the weight of the heavy duty cast iron drainage grate while adding strength and durability. The hinged operation is ergonomically preferable to complete grate removal and means the operation is easy for one person. One person can open the grate with a hook and remove it. The hinged drainage grate opens to 100° and features a safety catch at 90°, where it can also be removed.
