How to choose the size: It is recommended to match the depth of the partition with the length of the bracket to ensure maximum load capacity. Extending the depth of the diaphragm will increase the torque of the support arm. As the torque increases, the load capacity decreases (leverage principle). Complete models and solid support: Models include 450mm foldable flat supports to meet different sizes! Maximum load capacity is 330 lbs / 150 Kg. To increase the load capacity, you can increase the number of brackets between the bays. Space saving: the foldable flat bracket only needs one mounting surface, which takes up very not a lot of place. You can use them to extend workbenches in garages, laundry rooms, kitchens, garages, boats, receptions, backyards, campers, grills, trailers, bedrooms, balconies, bathrooms, etc. Folding up when not in use can save most of the space.
