Mount your hayracks on wooden deck rails with this pair of iron brackets!  The brackets for wooden deck rails can be used to support any size hayrack without damaging your wooden railings. The top of each bracket has an adjustable slide that moves to fit the exact width of your railing, then it fastens securely with a locking screw. At the rear, the bracket clamps around the underside of the railing. The lower part of each bracket goes down straight and rigid, holding your hayrack away from contact with the railings.

Each bracket is 13" tall. Adjusts across top from 3 1/4" to 5 1/4" wide. Grips lumber up to 1 3/4" thick.  For thinner lumber, shims can be inserted to achieve a tight fit.
 
One (1) Pair of brackets holds up to 200 lbs!
