The kit features the Simpson Strong-Tie Rigid Tie RTC2Z corner connector that makes it easier to make strong and durable corner connections with 2x4 lumber using no angle cuts or bolts. Each kit contains enough RTC2Z connectors to build one workbench, 2 kits are required to build a four-shelf unit. With this WBSK kit, a professional quality project can be customized and completed in a couple of hours. When lumber is added, DIYers can customize and complete the project they need to fit their space. (Lumber and fasteners for attaching plywood and pegboard sold separately.) Each kit includes 8 Rigid Tie RTC2Z connectors and 100 Simpson Strong-Tie #8 x 1 1/4 in wafer-head screws. Kit contents can be used to build other helpful projects, such as potting benches, garage organizers and bar carts. Strong enough to hold heavy boxes, tools and machinery. Projects can be built at different lengths to accommodate your needs. The galvanization process of the RTC2Z connector offers extra corrosion resistance.
