MDI Compact Signs are permanently mounted to foldable crossbracing, allowing the sign to fold down for storage. The crossbracing is equipped with a Single Trigger Release Mechanism for easy deployment and takedown with just the push of a button. The MDI Compact Sign is used with WindMaster Sign Stands Models 4814DLK, 4814HDK, 40CAM, 5012NS, or 5012SS. The sign can be stored right in the stand, ready for immediate use.

The P4N-03989 plastic pocket sign comes complete with fiberglass crossbracing and a 4-pocket style. The 4-pocket style comes in two pieces – sign and cross-brace. The sign is deployed by inserting each end of the cross-brace into the pockets on each corner of the sign.
