No screws or glue required. Simply slide the Thigh Pad on over the bottom of the holsters belt attachment, until the tabs at the top of the extended arms click into the pockets and keep the Thigh Pad in place. To remove, pull those tabs up and out of the pocket they are clipped into, and slide the piece down and off (it may be a tight fit, to prevent wobble)
Suitable for use on both Right-Hand and Left-Hand holsters.
