The maximum design capacity for two Monster Brackets supporting one load is 750 lbs. This capacity can be achieved if the following construction practices are followed:

 

• Two (2) Monster Brackets supporting one load on one or more shelves
   

• Both brackets are secured to a wall stud with two (2) 3/8" lag screws per bracket; said screws achieving a minimum of 3" penetration each into the wall stud
   

• Wall mounted shelf ledgers are secured to the wall studs with 3/8" lag screws with washers at 16" on center, said screws achieving a minimum of 3" penetration each into the wall studs
   

• 1/2" minimum plywood shelving; said shelving fasted to both the wall mounted ledger and the outer ledger with GRK #8 2.5" screws, or equal
   

• Lower hanging shelves hung by a minimum of 3/8" threaded rod with nuts, washer, and fender washer top and bottom.

 

Note: Ledgers that are the support beams for the shelves are shown as 2' x 4' lumber (but larger lumber may be used). Purchasers and/or installer are solely responsible for load calculation, the spacing of brackets, and sizing of structural lumber.
