Stop storing your sewer hoses in your compartments or bumpers. Try the EZ hose carrier from Valterra Products! Fits all 3" drain hoses and fittings with the exception of one-piece 90-degree sewer fittings. Inner diameter: 4.450". Comes assembled with mounting brackets for easy installation and includes self-tapping screws. Easily adjustable to adapt to the best mounting location and hose size! Comes with quarter-turn twist lock caps with straps. Both caps are vented to prevent moisture from building up in the carrier. Each cap has a loop that you can add a padlock to for extra security. Works great, especially if you're storing your expensive fishing poles (store without reels attached)!!
