Mainsheet swivel jammers from highest specification marine aluminium alloy designed to take heavy mainsheet loads with ease.
The ball bearing bases have a double row of Delrin balls giving super smooth swivel action under the heaviest load conditions with integral "clearways" for drainage. Cleat angle can be adjusted for correct lead by use of varishim (supplied).
Three models (R1961, R1962, R1963) incorporate a unique facility that enables the angle of rotation to be customised to suit individual needs allowing the angle to be limited anywhere from 320 down to 220. Simply alter the size of the moulded quadrant before fitting (Reg. Design). Input from the RWO race squad, has helped to create a new generation of Jammers. The R1965 incorporates a new base, with conventional single arm for mainsheet only.
