Restore smooth, stable and reliable roof operation in your wind-up camper with the JackaMast Telescopic Roof Lift Mast.

Designed as a replacement for worn or damaged telescopic camper masts, the JackaMast features larger internal support guides that help reduce the free play commonly found in older mast assemblies.

The built-in threaded roof mounting block also allows the finished roof height to be accurately adjusted to suit the camper’s existing canvas tension and side-door alignment.

Installation Information

Installation involves supporting the camper roof, removing one old mast at a time, feeding the new mast over the existing flexible pushrod and securing it to the lower mounting plate and roof connection.

For safety, only one mast should be removed at a time. The remaining masts and correctly positioned support props are required to support the camper roof during installation.

Professional installation is recommended where the installer is unfamiliar with camper roof lift systems, winch cables, roof alignment or corner-mast replacement.

Frequently Asked Questions

Q: What is the JackaMast used for?

The JackaMast replaces a worn, damaged or loose telescopic roof lift mast in a wind-up camper trailer.

Q: Does the JackaMast suit Jayco camper trailers?

The manufacturer’s installation guide is based on a Jayco wind-up camper trailer. However, Jayco models and lifting systems can vary, so the existing mast dimensions and mounting arrangement should be checked before ordering.

Q: Can it be used in other brands of camper trailers?

It may suit other wind-up camper trailers with a compatible telescopic mast and flexible pushrod lifting system. Jacka Industries recommends obtaining approval and installation directions for applications outside the supplied guide.

Q: What is the maximum travel of the JackaMast?

The maximum mast travel is 1080mm. If any existing camper roof-corner measurement is greater than 1075mm, contact Jacka Industries before installation.

Q: Can the roof height be adjusted?

Yes. The threaded upper roof mount allows each corner height to be adjusted. One complete rotation changes the roof height by approximately 1.25mm.

Q: Should all four corners be adjusted to exactly the same height?

Not necessarily. The manufacturer advises setting the roof height according to the camper’s canvas tension and side-door fitment. Factory corner heights may differ by up to approximately 20mm.

Q: Can I replace only one mast?

Yes, an individual mast can be replaced. During installation, only one mast must be removed at a time to prevent the camper roof from becoming unsupported.

Q: Are mounting plates and roof bolt kits included?

The installation guide identifies JackaMast mounting plates and the roof bolt upgrade kit as optional accessories. Check the selected product package before ordering to confirm exactly what is included.

Q: Can the original roof bolts and spacers be reused?

Existing bolts may be reused if they are suitable and in good condition. Any original spacers, brackets or mounting components must be correctly reinstated to maintain roof alignment.

Q: Does the mast require lubrication?

Yes. Apply a light coating of dry lubricant to the central and upper sections approximately every ten roof operations.

Q: Is the JackaMast waterproof?

The mast sections are not designed to be watertight. The canvas weather cover must be fitted around the mast when the roof is raised, and the lower mast opening must be properly sealed with silicone.

Q: Is professional installation recommended?

Yes. Installation involves supporting the camper roof and working with the roof lifting system, mounting plates, spacers and, on some campers, the winch assembly. Incorrect installation can cause roof lift failure or void the warranty.
