Adding a Rail stop to a 1010 rail will prevent your rocket from sliding down the rail too far.
This is a secure method to prevent you bottom railbutton from coming off the rail near the blast deflector.

A rail stop can be added quickly by simply sliding down the rail and locking in place with a standard 5/32 hex wrench. (available separately if needed).
It can be easily adjusted if needed even if the rocket is already on the rail. (that may require a second set of hands)

Once locked in place is it capable of holding up to a 200lb rocket!

Parts included are:

6061-T6 Aluminum Alloy spacer
Stainless Steel Socket Head Cap Screw
A slide-in T-Nut

Stops are available in unfinished aluminum or powder coated in Black, Lime Green, and Bright Yellow and black anodized ($1.00 additional)
