  • L-Bolt Anchors are used when new concrete pads are being poured for your cluster mailboxes.
  • The L shaped anchor bolt is inserted into the wet concrete so that as the concrete sets the bolts are secured in place.
  • If new concrete is being poured, the L-bolt is the best possible CBU mailbox anchoring option.
  • This option comes with 4 stainless steel L-bolt anchors that are 7 inches by 2 inches, 4 washers, and 4 matching hex nuts.
  • Upgrade your installation hardware by including two optional tamper-resistant nuts to prevent your CBU cluster mailbox from being stolen. Tamper-resistant nuts install easily but are hard to remove.
  • The nut is easily installed using a standard socket or wrench. The hex head breaks away upon tightening and leaves a non-removable cone.
  • The set of 2 stainless steel tamper-resistant nuts should be installed kitty corner from each other in order to deter theft.
  • Works great with CBU mailboxes, outdoor parcel lockers, and NDCBUs
  • Everything you need to safely and securely install your brand new mailboxes
