The WF-UP is a metal bracket used to secure plate casters in conjunction with the WF-LOW on Flexpipe structures, such as the W-4PSB and W-4PF.
WF-UP and the WF-LOW are installed with two M8-35B bolts and two M8-N nuts. This accessory is not for six-inch casters. The larger version of this bracket should be chosen if this is what you need. So if you are using W-6PSB or W-6PF wheels be sure to use the WF-LARGE product page.
