You can remove the bolts, and then the rivets and cap, but I just filed the cap away in the area of the underside of the track. This allows the traveller to come off, and the bolt heads stop the traveller normally. The stainless roller traveller is a good deal. I just wish they would put proper larrge diameter rollers to guide the traveler sheet. I used Hobie rollers and a home-made top strap which worked OK( hEADS OF BOLTS THU ROLLER FROM UNDERSIDE OF TRAVELLER CAR PLATE WERE GROUND DOWN TO CLEar track.)
