The Wall Control Slotted Tool Board Deluxe Hook Assortment includes 26 durable steel slotted tool board hooks and brackets that feature a scratch and rust resistant baked-on black finish. These more secure and stable tool board hooks are for use with the slots found in all Wall Control Metal Pegboard tool board panels. Wall Control Slotted Tool board hooks offer a patented engagement that requires two deliberate motions up-and-down to engage and disengage the hooks. This feature makes Wall Control Slotted Tool board hooks 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 1/4 in. pegboard accessories as well as Wall Control Slotted Accessories the Slotted Secure Tool Board Hooks included in this set are only for use with Wall Control Metal Pegboard Panels and Tool Boards.
