I think it is feasible. Whirlpool sells glides too. The IKEA kitchen staff told me to call Whirlpool for glides for their IKEA Momsig ovens made by Electrolux.

What I have seen so far is the glides snap on to the chrome wire side support that holds the trays, and then you place the tray on top, so the tray is raised by a fraction of an inch above where it was when it slid in the wire support slot.

Viking has them too. But as a first step, make sure that both width and depth of the oven are the same. For example, I know the Dacor 36" oven is deep enough to hold a full commercial-sized sheet pan, whereas many other convection ovens are not. So its glide rack would protrude too far in other ovens to be useful.

BTW, one disadvantage of glide racks is that they will be ruined if you leave them in the oven during a self-clean cycle.

Thanks to both of you for the great information & creative ideas!
