The Retract-A-Roll II in-van pneumatic retractable roller track from Ancra International features a Wear Guard air bag-protection jacket that prolongs the service life of this system-critical component by protecting it from damage caused by debris falling into the track channel through roller openings.

The air bag, which raises and lowers the rollers as required, is fully wrapped, preventing punctures from the bottom and sides, where they typically occur. Beveled roller openings also limit debris that can fall into the track channel. As a result, Ancra offers what it claims to be the industry's only air bag warranty — two years, no questions asked.

The Ancra system uses internal stops in the main channel to limit roller cradle lift. This design eliminates excessive stress on the top plate and uses 80% fewer top plate-retention screws, reducing the time needed for inspection and maintenance.
