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.
