marco.legio4 years ago000Hello all. After moving house, I only have one tree and now I want to buy the slackframe. Do I still need a biden screw or is everything I need included with a slackframe? Thanks in advanceShow in original language (German)AchimMeyer4 years ago000 Helpful answerYes, you need it. It should be 70 cm long and then screwed in at a 45 degree angle. Have a look at the AMAZON page under floor anchors...Show in original language (German)Comment1 comment
