The maximum load is 105 kg/pair. These load limits are used as general guidelines and are not intended as express or implied warranties. When these brackets are applied to furniture legs or narrow work surfaces, the effect will be better. If the legs are unsupported, greater spacing will reduce load capacity. Actual use conditions typically result in lower load capacity than laboratory conditions. 3. 90/0 adjustable, when the hinges of the folding table are folded, they will be wedge-shaped. This is a special design for leg extension. Cheng works better! 4.

Place them on a stand or table to fold legs on a table or bed, fold items on the table, fold table extension, etc. 5.
