Do it your seller's, please note, that all carriage bolt  heads must be ground to a diameter no larger than 15/16"to allow the bolt head to fit down in the knob so that it can fully open for a strong draft. Note we do sell a convenient, prepared bolt, hardware kit that can be purchased separately or included in some kits. Please note a bolt set is (2)   1/2"x 3"1/2
Carriage bolts and (4)  1/2" nuts.)
