The Eaz-Lift Scissor Jack Drill Attachment is an adequate replacement for the traditional hand jack that comes with many RVs and travel trailers these days. However, DO NOT over do it with the drill. Be careful not damage the scissor jack by slamming the screw in or out with the drill. These devices are not made to withstand the force. But as long as you ease it on and off, it’smuch faster than the traditional hand crank.
