These side tap spout kits are made with 12” Square Spouting, 10 Gauge material and they have a 12” square angle flange (with 4 holes drilled per side) on each end that should mate with most 12” rack and pinion gates in the industry.  The Basic spout assembly with hinge is approximately 11’ long and comes painted/ primed grey.  We recommend adding a turn down spout on the end of this assembly to divert your grain down for better and more even truck loading.  (purchase this separately)  Other products you may find helpful for  your side draw installation include (See "You May Also Like.."
