Mast colar system

Реферат: ABSTRACT OF THE DISCLOSURE A mast collar system for securement to a surface at the location where the mast extends down through the surface includes a rigid collar which loosely encircles the mast. Positioned in the gap between the mast and the collar is a resilient ring. An annular groove extends down into the ring and a spline is pressed down into the groove so that a fluid-tight gasket is formed between the mast and the collar. The ring or spline also includes a fin which resiliently engages the mast directly above the annular line of sealing engagement between the mast and the ring per se.
