Our Adjustable Stall Wall Bracket is made to hook over an 8 foot stall wall one inch to six inches wide. Just loosen the T-Handle Bolts and adjust the hook bars accordingly.  The Stall Wall Bracket accepts up to three Saddle Rack Tiers, two Blanket Racks or one Blanket Rack and one Saddle Rack Tier. Note: The Blanket Rack Spacer must always be used in between the Saddle Rack Tier and the Blanket Rack for proper saddle clearance.  See picture for your different options.
