When hanging with the 'D' ring system, a ‘false hanging wire’ must be installed on the frame so the wall mounted AG unit senses that it is holding weight. That pressure is achieved by mounting a small spring (Primeline Extension Spring, ¼” x 2  1/2” x .016”/6mm x 6.4mm x .4mm), about 2" (50mm) in length, on one eye hook on one inside edge of the frame, attaching a braided wire to the other end of the spring and to an eye hook on the opposite inside edge of the frame. The eye hooks can be placed anywhere on the frame, but the lower they are, the easier it will be to set the wire on AG and deactivate AG when moving the piece. There should be some slack in the wire as it hangs naturally. Place a straight edge (A) between the “D” rings of the frame. Then by placing your finger under the middle of the wire (B), lift it without stretching the spring and measure the distance between A and B. Place the straight edge on the wall between the “D” ring hooks and measure down the A-B distance and place a mark. That mark aligns with the screw hole on AG. Screw AG to the wall. Mount the frame on the “D” rings and reach up under or from the side and lift the false wire into the groove on the top of AG.  Pull the cord to activate AG.

When hanging from perimeter molding, use a single length of wire from the ceiling to run down through one “D” ring, across Art Guard, through the opposite “D” ring and up to the ceiling again. A vertical or horizontal piece of wood is placed between the top and bottom or sides of the frame, to which the AG unit is mounted. The screw hole on AG should line up directly between and on the same line (A) as the “D” rings. This will cause the wire to be raised once placed in AG’s groove (B). Prior to arming the unit, level the piece by sliding the wire left or right through the 'D' rings. Pull the cord to activate AG.
