Optional Peak Platform Assembly The peak platform is an option to the roof stairs and peak rails, and is to be assembled in conjunction with them. 1. The peak platform support ring is located similar to the peak rail tubes that are provided with the peak rail assembly, only it is positioned towards the bottom of the peak rail support posts and roof stair handrail posts. The support ring is secured to the posts using the half-round clips (234114) and ¼” diameter self drilling screws. First bolt the half-round clips onto all of the posts with the supporting ends facing inward towards the peak ring. Securely seat the supporting 1.66” dia. tube into the half-round cradles and secure with a self drilling screw that is drilled in from the backside. DRILL IN SELF DRILLING SCREW THROUGH PILOT HOLE IN THE POSTS (ALL LOCATIONS) HALF ROUND CLIP (234114) SUPPORT RING Figure 29 2. The peak platform deck pieces (234118) are evenly distributed around the peak ring as shown such that the amount of overlap between adjacent pieces is roughly even. The wider end is supported on the support ring, and the narrow end rests on the ribs of the roof sheets. To initiate the alignment, one deck piece should be centered on the top roof stair tread. There will be interference between the deck piece and the skid resistance indentations on the stair tread. The best way to overcome this interference is to shorten the peak platform deck piece enough to avoid the skid resistance indentations that are on the top surface of the stair tread. Secure the deck piece to the stair tread with at least two self drilling screws. SOME INTERFERENCE WITH THE SKID RESISTANCE INDENTATIONS ON THE STAIR TREAD WILL OCCUR IN THIS AREA Figure 30 Page 29
