MAILBOX BRACKET CRASH TESTS

Researchers conducted a total of 11 full-scale crash tests. Each test was conducted and evaluated in accordance with nationally recognized guidelines as contained in NCHRP Report 230. The purpose of the first eight tests was to determine the adequacy of a new, universal bracket developed by TxDOT to attach any size mailbox to the support post. Researchers conducted tests with one and two mailboxes of various sizes mounted on single support post, as well as on single support designs, and with multiple mailboxes mounted on a modified version of the Firesight Tubular Support. The modified installation consisted of a 'replacement footing' to facilitate use of salvaged parts from damaged supports and to minimize cost of replacement following a vehicular impact. A size 2 mailbox supported by two steal winged-channel posts was evaluated in the tenth test. A 1/4-inch (0.64 cm) thick steel plate 'vandal-proof' mailbox mounted on a single support was evaluated in the final test.
