The Beaver Squeezer grapple was developed for my own tree service. When I began looking for a grapple attachment, I found only a few. Of those few, they either did not offer rotation, or those that did rotate did not have the ability to secure logs BOTH horizontally and perpendicular to the frame of the attachment. So I designed and built one myself. We spared no expense in workmanship or materials when building this attachment. It was built solid to give you years of performance.
