75mm Stainless Steel Chimney Cover for Roof Air Vent

[Fully Extended and Robust] The extended length of the drawer slides is equal to the closed length. Made of high-quality cold-rolled steel. Thickness: 13 mm, twice that of a standard slider; Load capacity: 45 kg (100 lbs), 1.7 times that of a standard slider. With a 30-year lifespan, the drawer slides have been successfully opened and closed over 100,000 times through testing. [Rust Resistant and Durable] Electrophoretic surface treatment prevents direct air contact and improves resistance to oxidation and corrosion. Rubber brakes at the end of the slide prevent automatic opening and reduce noise to 35 decibels for a more comfortable home environment. [Removable Ball Bearing Drawer Slide] The slide's interior is designed with two sets of ball bearings, all made from solid steel balls. In addition to maintaining the smooth operation of the slide, they can also effectively increase the slide's load capacity. The back of the slide rail is designed with a removable button that can be pressed out for easier installation and cleaning of the drawer. [Installation Guide] This product is suitable for product lengths ≤ cabinet depths. Mounting space to the left of the drawer: 0.5" (13 mm), mounting space to the right: 0.5" (13 mm). [Product Improvement] The drawer slide is equipped with a switch function. When using, you must first press the drawer inwards, and the drawer will automatically extend. You can then pull the drawer out; otherwise, the drawer cannot be opened because it has a locking function to prevent young family members from injuring themselves when opening the drawers.
