The AC394 utility shelf is robustly secured by four bolts to a welded accessory ring positioned near the top of all geuine Astro Engineering observatory piers. The tray is 48cm (nearly 19") in overall diameter and has 15cm (6") of useable width - that gives you over a metre (about 40") of convenient storage space around the pier!

The utility shelf is made of steel and has the same black powder coat finish as the piers and has an edge security rim to make sure your valuable equipment stays off the floor!
