Underfloor inspection hatch without a frame

We are introducing a revamped construction method with an evolved indoor floor inspection opening.

This product features a structure that traditionally used a support frame when installing the outer frame, but has now eliminated the need for a support frame by adopting a plastic receiver. Furthermore, the sliding structure of the plastic receiver allows it to closely adhere to the joist, securing both the outer frame and the plastic receiver in place. Additionally, the method for installing the inner lid and the rotating handle has been completely revamped, enabling easy and stable installation. 【Features】 ■ Revamped installation method ■ Elimination of the support frame by adopting a plastic receiver ■ Close adherence of the joist to the plastic receiver, securing the outer frame and plastic receiver ■ Revamped inner lid installation method and rotating handle ■ Enables stable installation *For more details, please refer to the PDF document or feel free to contact us.
