    Since the factory collimation and locking screws are close together, knobs must be staggered in height. The locking knobs protrude further than the collimation knobs. Locking knobs are now red for easy identification.
    Early versions of the R200SS primary use metric M5 screws for primary adjust instead of the M4 screws that we provide. You can pull a primary adjust screw, which is the Phillips screw, and measure the thread diameter. If you need M5 primary adjust screws with your knobs, please enter a note in the window provided during checkout.
    Protect the locking knobs from damage, and do not support the OTA using the locking knobs as feet.
