These attach with a very professional looking back plate with screws that lock into threads on the front plate. Very reliable and easy to attach. These are very high quality and won't disappoint. These are very easy to install! Please see the photos. The strap ring is just under 1" (inside) across the top, so these would work well with either 1" or 3/4" straps & bag handles. Measurements: Inside measurement of strap ring: 7/8" (23 mm) Overall Length: 1 3/4" (47 mm) Overall Width: 1 1/8" (27 mm) Channel thickness: 3/16" (4 mm) Each anchor comes assembled with 2 screws. Make sure you stabilize the insertion area on your fabric so that it is strong and durable (peltex or similar between layers). Remove the 2 screws and back plate. Use the back plate to mark holes, and a leather punch to cut holes the same size as the threaded "columns". Use glue on the inside of the connector and back plate, and a thread locking liquid like "loctite" to keep screws secure.
