Triple-fold full-extension design: The drawer slides adopt a three-layer retractable design. The total length undeployed is 30cm, the total length fully expanded is 60cm instead of 60cm unfolded, the width is 4.5cm, and the thickness is 1.27cm. It can be installed directly on the side plate and turns smoothly. High Load Capacity: The drawer slides are made of high-quality cold-rolled steel. The surface is electrophoresed and finished. It is wear-resistant, rust-proof, durable and not easy to break. Strong load-bearing capacity, a pair of slide rails can bear 45 kg. Sturdy ball guide rail design: the steel ball ball design is used to reduce the friction generated when the drawer is opened and closed, reduce noise, and make the drawer slide smoothly and quietly. Soft and silent shock absorption: The unique roller bearing design can ensure the smooth sliding of the drawer rails, and the wear-resistant rubber pad has the effect of shock absorption and noise reduction, which can prevent excessive noise caused by closing the drawer violently. Easy installation: Install the outer fixed guide rails horizontally on both sides of the drawer and fix them with screws, install the inner fixed guide rails on both sides of the drawer, align with the fixed guide rails in the middle, and then drag them in parallel.
