We can create custom designed multi-opening mounts, we'll just need a rough diagram which indicates how you'd like the mount to be laid out, along with a few measurements. This page details how to do that. Please provide all measurements in mm.
If this mount is to go into a frame that you already own please also provide us with external dimensions of the mount. These dimensions should be identical to your existing glazing or backing board dimensions.
We need to know the dimensions of each of the openings through which the items you're framing will be seen. We need to know the height and width of this opening. Remember, the size you give us is the size we will cut, so make sure that the opening is slightly smaller than the picture that you're framing or it will fall through the hole!
Gaps between each opening
We will also need the measurements of the distance between the openings.
Distance between opening and edge
We will require the distance between the opening and the edge of the mount.
