| Barton Size 2 Ball Bearing Mainsheet Tracks    Fitting Barton Marine's new  removable track couldn't be simpler, End plates are bolted either side of the  cockpit, on the cockpit wall, the track is then slid under these plates and  lifted vertically, which automatically locks it in position. To remove the  mainsheet track, you just push in the locking pin on either side, lower the  track and slide it out of the way.                                                                Use beam track when spanning  cockpits or companionway hatches, where unsupported length is required                                                                               Max unsupported length: 700mm                                                                          Width W: 26mm                                                                               Width W2: 34mm                                                                               Height: 34.5mm |
