The 1in x 1in C-Bracket Slotted Metal Pegboard Hook for Wall Control"s Pegboard and Slotted Tool Board is a great tool board accessory for narrow items that feature a head larger than 1in x 1in such as socket wrenches. Wall Control Slotted Metal Pegboard Hooks feature a scratch and rust resistant baked-on black finish. These more secure and stable toolboard hooks are for use with the slots found in all Wall Control Metal Pegboard tool board panels. Wall Control Slotted Toolboard 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 Pegboard 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 1/4in 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.
