If there is no more space in the trap stopper for the cunningham, barberholer or the tackline, it is usually necessary to remodel and make space for more stoppers. Not only must the limited space next to the companionway be taken into account, but the sprayhood may also need to be modified. With the so-called BoBase from Loop Products, the expansion should be much easier.
Because the base fits under Spinlock's XAS stoppers. Only 30 millimeters longer screws should be required for this. Constrictor clamps are installed in the body. The line is fixed in a braided sheath due to the friction. This hose is stretched forward with an elastic band, so there must be at least 40 centimeters of space between the stopper and the deflector on the mast. The sheath braid can be relaxed using the control cord, thus releasing the cord in it. Due to the control cords, there is always one constrictor less space in the base than there are bushings in the clamps above.
The price for the extension of a 3-XTR clamp consists of the base itself for 137.85 euros, two holders for constrictor stockings for 45.70 euros and two constrictor kits for 106.25 euros. That makes a total price of around 442 euros.
