Talk Morgan Forums Community The Malvern Arms Ideas Please : Low profile carpet castors/sliders?

A small appeal for creative ideas please.

Here's the challenge: These cold winter evenings are making schlepping down the garden to the studio a less than attractive proposition, so I'm doing more guitar playing in the house. Ergo, I have just ordered a new gizmo, a Headrush Pedalboard for those of you who know about such things. I want to use it in the lounge, which is carpeted. It is a fairly significant size and weight, 30cm x 60cm, 7kg, so it's not really the sort of thing to easily pick up and move around, and 'er indoors is not going to be best pleased if I leave it out in the middle of the room when not playing with it (trip hazard). But she'll be very happy if it can simply slide away and live in front of the amp when not being used.

First thought was to sit in on a board with castors underneath, but all the castors I can find are a good dealer taller than I'd like, this thing needs to be as close to the floor as possible. Does anyone know if there are any really low profile low friction slidey/rolly type things that I can use to be able to move it about relatively easily? All ideas gratefully received, if not actually acted upon
