brand name is ADCO 3 layer laminated heavy duty vinyl..had to drill 14 screw holes for the snaps, Zippers on three sides. Understand that the snaps are the best installation.Suction cups and velcro are the other two methods and have been told neither works very well.
Size for the 3400 is 64"H X 236"L No alterations, easy fit..takes some measuring for proper alignmnet of the snaps..two people make the job easy..
