We would like to introduce the "Safety Walker Grip Design Square Manhole Cover Type with Bolt Fixing" handled by Okagreat Co., Ltd. The "Grip Design Square Manhole Cover Type with Bolt Fixing" is suitable not only for site-cast drainage manholes but also for various types of bolt-fixed manhole covers, sump covers, and specially sized square covers.

Additionally, the design minimizes the likelihood of stones and debris getting stuck in the grating, preserving the aesthetic appearance. Multiple slit holes are made in the special steel plate "ribbed steel plate" on the top surface, balancing drainage capability and strength. It has also been reported that the anti-slip effect exceeds that of conventional types. The bolt-fixing design also helps prevent theft. 【Features】 ■ Safety (difficult to break due to panel structure) ■ Reliability (non-slip due to patterned steel plate) ■ Strength (up to maximum T-25 load) ■ Lightweight (lighter than fine types) ■ Aesthetic (prevents clogging) ■ Damage prevention (distributes force over a surface) *For more details, please refer to the PDF document or feel free to contact us.
