Simple design, innovative features and state of the art materials give the “Slick Release” secure holding of the tiller extension on the tiller whilst still maintaining its “simple to remove” objective. The ingenious and innovation design utilises the tiller extension joints “rubbery” properties to get a positive and secure “click and closed” locking of the tiller extension into the fitting. The distance betweene the hole centres is 64mm - so a little different to the standard joint fittings.
