Product Detail Locking Sides The frame can be expanded and firmly locked, and so can the casters. The built-in hook allows you to connect two or more Conveyor Rollers together, providing you with almost unlimited moving options. In this way, you can move the materials throughout the whole workshop! Handles Big Jobs The 22” wide rollers are smooth in operation, allowing your material to glide with ease. And it can hold up to 300 lbs., so large jobs are not a problem. Folds for Storage When you’re finished using it, the Conveyor Roller folds away for easy storage until next time. 360° Universal Wheels This commodity is equipped with 360° no dead angle universal wheels, and can be moved freely to the place where you want to transport goods. Four independently adjustable height legs. Each leg is equipped with an adjustable-height adjustment rod, which can set curves, inclinations or height reductions to adapt to the uneven floor surface, and guide the goods to the place you need. Mobile Out-feed Roller Use the conveyor roller as a mobile out-feed table for large boards or sheet material. Simply adjust the height of the rollers level with your table saw to handle the big jobs easily.
