All Caboose Industries ground throws are molded of strong, self-lubricating black Delrin. An external cam provides maximum life and travel for each model. The ingenious design provides a positive lock in both straight and curved directions of throw, effective from 10° above horizontal to the full down position. A detent assists in holding the handle horizontal for installation purposes.
Caboose Industries ground throws are useful in a variety of scales and applications. All Caboose Industries ground throws are available in sprung and rigid configurations.
Sprung ground throws (Series 200S) feature two internal stainless steel springs to take up the overtravel and maintain tension upon switchpoints against the turnout stock rail. The springs are preloaded to a 6-ounce force, assisting in good electrical contact between points and stock rail and aiding in turnout installation.
Rigid ground throws (Series 100R) are fully-functioning stands that require the hobbyist to supply a spring link between the slidebar and turnout throwbar. Rigid models are recommended when the ground throw must be mounted some distance from the turnout; normally, ground throw motion is transmitted via a spring wire running through a tube to the turnout mechanism.
Standard Ground Throws
Caboose Industries standard ground throws are designed for direct connection to the turnout through a pin on the slide bar. They are available with three different amounts of slidebar travel: .190" for HO and S scale, .280" for O, and .135" for N, in both sprung and rigid configurations.
Standard Ground Throws With Selectable End Fittings
These Caboose Industries ground throws include a shim to raise the stand to tie level and five different end fittings for connection to most commercially manufactured turnouts: a hook end for Atlas, blade for Roco, hole for PECO, small round pin for Micro Engineering, and round pin for Shinohara and others. They are available with .165" travel for HO and N in both sprung and rigid configurations, and with .135" travel for N scale code 55 turnouts.
Ground Throws With Contact
Caboose Industries offers ground throws with SPDT (Single-Pole Double-Throw) contacts suitable to power a turnout frog, signaling system, or relay coil.
