Feature: 1. MAXIMUM LOAD CAPACITY 120KG: Strong, cold rolled steel plate measuring 2 mm thick is used to make the slide rail. During full load push pull testing, the slide rail can keep your drawer stable and secure even if carrying a weight of 120KG and required 800000 times. Our slide rails are built to last a very long time. 2. 3 TIMES FULL EXTENSION: The slide is 1000mm long, and the full extension is 2250mm long. In addition, because the slide rail can be fully extended, the drawer can be fully pulled out, making it simple to access and store the storage space of the entire drawer. The fully extended length is purposefully designed to be more than twice the closed length of the slide rail, leaving enough space for installation to allow for space to spiral into the stairs. 3. RUST PREVENTION AND SMOOTHLY OPERATION: Our slide rail has better rust prevention and oxidation resistance than other slide rails due to a special electrophoretic coating surface treatment. The interior of the slide rail is filled with industrial grade solid steel balls, which not only reduces frictional resistance and makes sliding smoother and quieter but also significantly boosts the load bearing capacity of the slide rail. 4. APPLICABLE SCENARIO: Suitable for cabinets under stairs and any staircase cabinet, achieving the miracle of staircase storage space. Also suitable for heavy duty drawers such as wine cabinets and wardrobes that require strong load bearing capacity. 5. EASY TO INSTALL: With a compact size and a fine workmanship, this cabinet slide rail can be easily installed for convenient use, ensuring a long service life.
