STAIRS/STEPS MADE EASY

STAIRS/STEPS MADE EASY AND MOVABLE WITH THE "STRATTON BRACKET®"


1. Bolt the "Stratton Brackets®" to the deck or house, to accommodate the steps.	2. Set the steps into position, place a 2x4 into the brackets and fasten the 2x4 to the stringers.	3. Add the last tread and the steps are complete, they will also be movable.

**Typical Building Code Requirements**
The building codes typically require that decks be able to support the same live load as the rooms to which they connect. In a residence, that's 40 psf. for a 300 sq. ft. deck, that's a total of 12,000 lbs. Take, for example, a 2 by Southern Pine deck ledger board attached to the house framing. With a 1/2" diameter bolt and a single shear applied perpendicular to the grain for "normal"duration, the allowable shear load in the bolt is 330 lbs. Of course, the bolt itself could handle many times that load, but what will fail first is the wood; that's what limits the capacity to 330 lbs. For a deck with joists spanning 14 ft. with 2x10's 16" on-center and 2x6 decking, the weight of the deck itself is approximately 7.3 psf. Add this to a design live load of 40 psf, and the total load is 47.3 psf. One half of this load must be supported by the ledger board at the house. Simple multiplication (14 ft. x 47.3 psf x 1/2) gives a load along the ledger of 331 lbs. per foot. The "Stratton Bracket®" greatly increases the "shear" of the wood because the wood "sits" in the brackets.
