Spacing holders
GeckoTeq is the specialist in spacers. With suspension systems, the top and bottom of the plate often hangs flat against the wall. With some other systems, the top of the plate can hang slightly loose from the wall and the bottom can rest against the wall. This is not a pretty sight and there are spacers to prevent this.
Spacing holders can be supplied in various sizes and can also be used beautifully with transparent material or glass. Even the accompanying Allen key has been thought of.
There are also simple self-adhesive plastic spacers (PVC Bumpers) available that you can stick to the bottom corners on the back.
In all cases, your artwork will hang neatly parallel to the wall.
