I couldn't get what I wanted from my usual supplier, which was fifty 4" castors. So I called Penn, I had been shown a new wheel at the last Plasa show. Anyway, phoned yesterday and they arrived this morning. These castors have the usual blue Guitel wheel but the frames are really heavy duty. Each wheel is rated at 250K, and the centre spigot is strong. They also turned out to be the cheapest wheel I've bought for a long time. So, have a look at the Penn wheels. The one's I have aren't shown on line. So you'll have to ask. Well worth a look.
Peace and goodwill to all speaker builders
