"Destroyer Jerry Can mounting brackets allow for easy attachment of Jerry Cans to Destroyer carriers. The Jerry Can mounts are passenger and driver side specific and can not be switched from side to side. With the new Destroyer carrier design, Jerry Cans can be adjusted vertically up and down with a maximum travel of 14"" inches. Gas cans can be easily removed or adjusted by loosening the mount bolts attached to the carrier. Mounts work with 5 gallon Jerry cans. We recommend using 5.3 gallon Wavian Jerry Cans for best results. Dimensions are (L x W x H) 6.50"" x 13.50"" x 18.50"" Any Nato style gas cans within these dimensions will fit."
