Holt Allen's Large Halyard Rack is made of anodized aluminum and has ten teeth. Swage a long loop onto the end of your wire halyard and attach a strong 1/8 in. (3mm) or smaller messenger line to use to pull the halyard and loop down and out of the mast under load so that it can be hooked to a tooth on the rack, to set the desired tension.
The track is mounted on the side of the mast. This 10-tooth model is slightly less than 5 in. (127mm) long.
