The photos of the sliding elements 1 and 2,5 show pattern of three little holes, the sketup files don't. Are these holes necessary, for what are they used?
|AL angle 1x1x1/8||7||8-ft||N/A||OnlineMetals.com||architectural aluminum 8-ft. lengths|
Does this mean 35-ft. are needed?
For the qty x length of angles listed in the previous table, 7 pieces of 8 ft each are needed, 56 ft total.
For perforated angles, lead nut mount and coupling nut clamp Aluminium angles with 1"x1", 1/8" thick are indicated. But in the templates for lead nut mount and coupling nut clamp it seems that are smaller angles are used. What are the right measurements for these parts?
