Security Metal Frame Kit includes
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.
