The Wall Control Pegboard Paper Towel Roll Holder and Dowel Rod Pegboard Shelf Assembly for Wall Control"s Pegboard and Slotted Tool Board is made from heavy duty 14 gauge steel and offers great pegboard shelf storage as well. Unlike most pegboard brands that fall short when it comes to shelving, Wall Control pegboard shelves are heavy-duty and up to the task with their solid construction and attractive finish. The Wall Control Pegboard Towel Rod Holder Assembly features a 4in removable shelf and accommodates conventional paper towel rolls as well as clothes hangers and any other items that can be hung on a 1in diameter dowel rod. Wall Control Slotted Metal Pegboard Shelves and Supplies feature a scratch and rust resistant baked-on finish. These more secure and stable toolboard accessories are for use with the slots found in Wall Control Metal Pegboard tool board panels only. Wall Control Slotted Toolboard accessories offer a patented engagement that requires two deliberate motions up-and-down to engage and disengage the hooks. This feature makes Wall Control Slotted Pegboard accessories less likely to fall out of the tool board than conventional peg hooks that can easily fall off when tools are removed. Although Wall Control Metal Pegboard Panels will accept conventional 1/4in pegboard accessories as well as Wall Control Slotted Accessories the Slotted Secure Tool Board Shelf Assembly included here is only for use with Wall Control Metal Pegboard Panels and Tool Boards.
