These stringers are punched with an extra wide punch to allow further rackability of a panel section. STANDARD panels will rack 12", allowing the pickets to remain parallel with the posts while the rails follow the conour of the ground - upto slopes of a 1:6 ratio. These double stamp rails will allow the panel to rack upto 45 degress - a 1:1 ratio. 100/401 style sections will have 3 stringers, while 200/211/400/402 styles will have only two stringers. If you wish to order the section pre-assembled with the double stamps rails, add a letter "B" before the "S" in the part number. i.e. J101RS would bae J101RBS. Double stamp rails and sections are more expensive because of the extra step, so make sure you only order the numbe of sections required for your hillside. |
