18 mm Switch T-Track 
Battcar Systems
For masts with sail grooves, 18 mm slug-mount track 
uses a unique system that allows mast-up installa-
tion. Use high-load slug-mount tracks on boats over 
12.2 m (40') at sail headboard locations at full hoist 
and headboard locations when sail is reefed. Drill/tap 
track and switches fit masts without sail grooves. 
Join drill/tap track sections with splice links. Order 
one per track section. Boats with larger sail areas 
should use long switches to accommodate more 
cars.
Mounting Kits and Endstops
Slug mounting kits are available for flat or round mast 
grooves. Order one kit per track section.
Switch track includes screwpin stops for easy car and 
sail removal below switch. Stop at masthead also 
included.
About Switch T-Track Battcar systems: see feature pages at 
beginning of this section.

** Use HC8811 high-load track on upper part of mast to reinforce HL system headboard locations. Mount using 50 mm hole spacing at 
headboard location at full hoist and headboard location at each reef point. Reduce weight in other areas by alternating holes to 100 mm spacing.     
***Switch may be shortened to 605 mm (23 13/16").
