The Kensington trailer organizer has plenty of room to store all your supplies with two large pockets in the top row and five pockets in the middle and bottom rows. This organizer easily fastens to the stall wall or trailer door with D rings on each end. Fold our organizer in half, lace the 1" nylon web strap with a snap through each D ring, and carry your supplies with you from the trailer to the arena and back to the stall. The strap also makes it easy to hang your organizer from any pipe corral. The mesh also keeps dirt and grime from accumulating in the bottom of the pockets. You won't find a more functional and convenient organizer anywhere. Size 40" x 27". You can use it to carry hay as well!
