About the A4:

Made from the highest quality maple, this loom features an innovative tie-up system, using “snap chains” for a quick, simple and secure tie-up for any treadle to harness combination. The friction brake maintains excellent tension control, and an adjustable beater accommodates reeds of different heights and widths. The suspended harnesses and pulley system make the jack-action light, quiet, smooth and rhythmic. The castle tool tray is easy and convenient for storage of shuttles, bobbins, and sley hooks. This loom is easily folded while fully warped, leaving the tie-up intact. Tilt it on its wheels, roll it to a workshop, unfold it, and you're ready to weave! Limited floor space? It can be folded and tucked away.

A dream of a loom

Learned to weave on a small Harrisville loom like this one, and absolutely loved it!
