Maglock with fixing lugs? Help

[skiversinc]

I'm hoping someone can help me out.
I'm trying to track down a model number for a slimline maglock which has the mushroom shaped mounting lugs on the top.
These are the ones where the top plate is fixed to the frame & then the lugs on the maglock slot into the corresponding holes in the plate.
I've seen them fitted on old doors that I have to change, but I can't seem to find them at our suppliers at all. All the ones I seem to get are the standard 2 screws to hold the maglock to the plate which doesn't help me in the environment that they're being used in.

I think Deedlock did them but I can't find a part number anywhere.
Can anyone help please?

I've not got a picture, sorry. Basically, they look like a normal maglock, but on the top is what looks like a pair of oversized screw head protruding out. This slots into the mounting plate and the screws on the end are only used to stop it sliding backwards & forwards.
