Security Kit Lock-In Metal hardware will fit on all currently manufactured metal frames generically designated as #11 Profile moulding. This includes the metal moulding currently made by Nielsen, Clark, Designer, Alumaframe, Global Art, MCS, Decor and most OEM manufacturers. The #11 Profile category (and compatible profiles) constitute probably 95% of the current metal moulding market.
As long as the corner hardware and channel on the back side of your metal frame looks like this and the channel is 3/8" wide, Lock-In hardware will fit.
If you are installing older metal-framed pictures, you should be aware that metal frame moulding design has evolved over the years and our Lock-In T-Head Screws and Wall Brackets may not fit inside the back channel of certain older, now obsolete style metal frames (typically pre-1980 manufacture).
There are a small number of these older extrusion profiles still being made, the so-called #186 Profile and #444 Profile. These profiles have a narrower back channel, measuring about 1/4" wide, compared to the standard 3/8" wide universal channel of the #11 Profile. Lock-In hardware will not fit on #186 or #444 profile metal frame moulding.
Lock-In Hangers cannot be used on low-end crimped corner metal frames (also called "back-load" or "back-loaded" frames). Back-loaded metal frames do not have a universal channel at all and look like this at the corners.
- Mark the desired
position of the top corners of the frame on the
- Drill a 1/4"
dia. hole in the wall about 1" down and 2-3" in from
sides of each these marks. (A 1/4" dia. hole is usually
sufficient for drywall--for harder surfaces or if the
plastic anchors start to deform when hammering them in
during Step 3, re-drill using a 5/16" drill bit). It
is very important that these two holes be as level on the
wall as possible.
- Attach the two
wall brackets at these holes so that the flanged ends of
the brackets face up and away from the wall, using the 1"
wall bracket screws and (red) plastic wall bracket
anchors provided. Take care to hammer the anchors in
gently until they are just flush with the wall surface.
Do not over tighten the bracket screws.
- Hang the frame
on the wall brackets so that the flanged ends of the
brackets are seated snugly inside the back channel of the
frame's top rail.
- Check for level.
If the frame is not quite level, small adjustments are
possible by removing the frame from the wall, loosening
the wall bracket screws slightly, shifting the brackets
up or down as needed in their slots, retightening the
screws and replacing the frame on the brackets.
- With the frame
hung level on the wall brackets, lightly pencil-mark the
wall at the centerpoint of the frame's bottom rail where
the rail's back edge touches the wall.
- For larger metal
frames, an extra (fourth) mounting point should be used
on the frame's bottom rail to make the frame more stable.
Extra T-Head screws and anchors must be ordered
separately (see above). For larger metal frames using an
extra T-Head screw, make two pencil marks during Step 6,
spaced an appropriate distance apart, rather than one at
the midpoint of the rail and expand Steps 9-13
- Remove the frame
from the wall.
- Measure the
distance on your metal frame from the outer edge of the
frame to the center of the channel (this dimension can
vary with different types of metal frames). Transfer this
measurement to the wall, making a second pencil mark up
from the one made in Step 6. Erase the bottom
- Drill a 5/16"
dia. hole at the pencil mark made in Step 9 and gently
hammer the (blue) T-Head plastic anchor provided into the
drilled hole until it is just flush with the wall
- Thread the
T-Head screw provided into the plastic anchor until about
3/8" extends out from the wall surface. Start the T-Head
screw first by hand and complete using a Security

- Again place the
frame over the top wall brackets. The bottom T-Head screw
should now be in position within the back channel of the
frame's bottom rail.
- From the right
hand side, slide the Security Wrench up underneath the
bottom edge of the frame and, without lifting the frame
away from the wall, engage and rotate the T-Head screw
clockwise one-quarter turn to a vertical position. The
frame is now locked to the wall.
