LedgerLOKs should be installed using an impact driver or high torque, 1⁄2" variable speed drill (at least 18V if cordless) or impact driver. Choose the proper length so that threads fully engage the main member (i.e., rim joist). Bring head flush with ledger using the flat head style. Not for use in masonry or concrete.
For detailed installation instructions, including fastening requirements, please refer to our Deck Ledger to Rim Joist technical bulletin. These instructions are included in all box and bucket packaging as well as being available for download from our website.
When using in non-ledger applications, a design professional should be consulted for all critical connections, which include the number and location of all fasteners to meet national and local code requirements.
