Ultra-Fab has introduced a new design for electronic tongue jacks using technology that the company claims makes the jack last five times longer than competing products.
The new feature allows RVers to lubricate the threaded rod that raises and lowers the trailer. As travel trailers become larger and heavier and slideouts become more common, consumers need a reliable, long-lasting tongue jack that will withstand the rigors of the camping lifestyle, according to Craig Searer, Ultra-Fab’s president.
Searer said the new Zerk technology is essentially a valve that opens under pressure to allow the lubricant to pass through a channel and be forced into the voids of the threaded rod. Grease fittings are permanently installed by a threaded connection, leaving a nipple connection that a grease gun attaches to. The pressure supplied by the grease gun forces a small captive bearing ball in the fitting to move back against the force of its retaining spring. When the pressure ceases, the ball returns to its closed position. The ball excludes dirt and functions as a check valve to prevent grease from escaping back out of the fitting.Research Campgrounds, Plan RV Safe Routes & Turn your phone into an RV GPS.
