An A4 frame which can save a lot of time by including loading instructions. This A4 frame can be positioned at the top of the Sheet Gauge using an appropriate recess. Several types of (plaster) sheets often end up on a trestle and on large projects it is therefore very important that the trestles are loaded as efficiently as possible, the sheets that are needed first on the outside, the others on the inside. That way you don’t have to hold a slab multiple times.
