Description Mount your STACK PACK™ storage items to the wall in your trailer, garage, or workshop with the FLEX FSM1501-10 STACK PACK™ Box Mount Kit, 10-Piece, which includes two Wall-Mount Rails and four pairs of Mounting Brackets. Featuring a 16-on-center design to mount on walls with standard 16-inch spacing without the guesswork, the wall-mount rail allows you to easily transition your STACK PACK™ setup from transport mode to its place on the wall in seconds without tools. The FLEX FSM1501-10 mounting brackets are built for durability and stability, featuring a heavy-duty all-metal connection with a 70-pound load capacity. The mounting brackets support mounting to STACK PACK™ Rolling Tool Box Mounts (FS1504, sold separately) and the included Wall-Mount Rails for easy transitions between setups without tools. Both the FLEX FSM1501-10 Wall-Mount Rails and Mounting Brackets are compatible with a wide range of STACK PACK™ items.
