These rail guides are precision CNC machined from black Delrin to a true NACA airfoil shape. Even the part going into the rail slot is airfoiled. Mounting is easier because you can align the guides with a line traced on the tube and aerodynamics is greatly improved over the round guides.
Delrin is an auto-lubricating material so slippery that the guides will slip off your hands if you don't take care when you pick them up!
These guides are designed to be mounted on large rockets (diameter over 100 mm) which require a large launch rail.
The package includes a pair of guides and two 6 mm socket flat screws. The screw head is perfectly flush with the guide once tightened, with a beautiful look.
