Coleman RV Rooftop AC Long Mounting Bolts (4-Pack)
Coleman RV Rooftop AC Long Mounting Bolts (4-Pack) — Product description
These are the long mounting bolts for Coleman rooftop air conditioners, sold four to a pack. When your RV's roof is thicker than average, or you've added a gasket during a reseal, the factory bolts can run out of reach. These give you the extra length to pull the unit down and seal it right.
These are the long mounting bolts for Coleman rooftop air conditioners, sold as a pack of four. If your RV has a thicker roof than average, or you've added a gasket or spacer during a re-seal, the standard bolts that shipped with your AC may not have enough reach to pull the unit down properly. That's exactly what this hardware is for.
A Coleman rooftop unit clamps to the roof with four bolts, one at each corner of the ceiling assembly. Those bolts run from the interior ceiling frame up through the roof opening and thread into the AC on top. As you tighten them, they draw the unit down and compress the foam gasket that seals it against the roof. Get that compression right and you've got a watertight, rattle-free install. Come up short on bolt length and you can't reach the right compression, which is where a leak or a buzzing unit starts.
You'll know you need the long version if your bolts bottom out or run out of thread before the gasket is squeezed to the spec your AC manual calls for. Thicker roofs, added underlayment, or a fresh gasket all eat into the length you've got to work with. Swapping in these longer bolts gives you the extra reach without forcing anything.
It's a set of four because that's what one rooftop unit takes, so a single pack does the whole install. Tighten them evenly, a little at each corner in a cross pattern, so the gasket compresses flat instead of cocking to one side. And don't crush it. The goal is even, firm compression, not maximum torque. Over-tightening squashes the gasket and can crack the shroud or the ceiling frame.
These are genuine Coleman RVP replacement parts, MPN 8333-3211. Because rooftop AC hardware varies by model and roof build, check your unit's installation manual to confirm the long bolt is the right call for your setup before you pull the old ones. If you're mid-install and the standard bolts came up short, this is the fix.

Frequently asked questions
What comes in this pack?
Four long mounting bolts, nothing else. This is the bolts-only pack (MPN 8333-3211), meant for replacing or extending the mounting hardware on a Coleman rooftop air conditioner. It doesn't include the AC, gasket, or ceiling assembly.
When do I need long bolts instead of the standard ones?
When your roof is thicker than average, or you've added a gasket, spacer, or underlayment during a reseal, the standard bolts may not reach far enough to compress the gasket to spec. The long version gives you that extra reach.
Why are there four bolts?
A Coleman rooftop unit clamps down with one bolt at each corner of the ceiling assembly. Four bolts do a complete install, which is why they're sold as a set of four.
Will these fit my air conditioner?
They're genuine Coleman RVP mounting bolts for Coleman rooftop AC units. Because hardware and roof thickness vary by model, check your unit's installation manual to confirm the long bolt is correct for your setup before swapping.
How tight should I make them?
Snug them evenly in a cross pattern so the gasket compresses flat, and stop at the compression your AC's manual specifies. Don't over-tighten. Crushing the gasket can cause leaks or crack the shroud.
Are these genuine Coleman parts?
Yes. These are genuine Coleman RVP replacement bolts, part number 8333-3211.
