APS - Schaefer Stand-up Blocks

Schaefer Stand-Up Blocks on T-Track Cars

Schaefer Lead Blocks on cars feature a plain-bearing articulating block mounted on stainless steel car with spring-loaded stop pins. Schaefer spring-loaded lead blocks allow jib and genoa sheets to be sheeted at any angle. Patented springcap design prevents the block from hitting the deck when sheets flog while raising sails or tacking. 360 degree block rotation. Heavy duty stand-up springs and hardkote anodized aluminum side cheeks.

Schaefer Aluminum T-Track

Schaefer's 6061-T6 Aluminum T-Track incorporates a concave shaped riser that allows it to remain steady for spar mounting, or easily accept sealant for mounting to decks. Available in durable, black hardcote anodized, or silver (clear) anodized.

The Race Track features more closely spaced holes to allow racers to fine-tune sails with three times the granularity of normal T-Track. Also works well with reefing blocks and spinnaker mast eyes. Available in black anodized only.
