3. Select Car & Purchase Requirements
Based on system size and purchase requirements, select a car and 
accessories that match track and load requirements. Select control 
blocks for the car. 
A kit contains car-mounted components to make a 2:1, 3:1, or 4:1 
system. 27 and 32 mm systems only.
Cars come standard with shackles for attaching the mainsheet to the car. 
Upgrade to a stand-up toggle with control tangs to attach high-performance 
ball bearing control blocks. See Purchase Selection Guides for examples 
and sizing. 
4. Choose End Controls
Choose end controls that mate with the control blocks on the 
traveler car for the correct purchase system, including a deadend, 
allowing clean-running lines. Use Carbo ball bearing end controls with 
toggle-mounted, ball bearing control blocks, or use ESP sleeve bearing 
end controls with ESP car-mounted, sleeve-bearing control blocks.
Options include end controls with attached cams, or purchase cams 
separately and mount remotely. See pages 256 - 257 for common systems.
5. Choose Endstops
Endstops are designed to absorb shock loads and should be installed 
when end controls are not used. Trim caps finish off track ends cleanly. 
Select high- or low-beam endstops/trim caps to match track. Low-beam, 
line-shedding endstops prevent snags. Sold in pairs.
6. More Information
Previous steps show the most common configurations. Other options 
include windward sheeting cars, soft attachments, coupled cars, track 
risers, and track splice links.
