I get a lot of inquiries for hammer extensions and this is by far the best unit I have found. Made for Bellm out of Silver anodized aircraft grade aluminum in the USA. I recommend these for G2 Contender, Encore and yes Prohunter models too and for both left and right hand applications. This unique "triple lock" fastening system creates the most positive grip for your hammer anywhere. Comes complete with set screws and allen wrenches as pictured.
