Where to buy Electric Heat Treat Oven Parts?

Specifically I'm looking for ceramic tiles or panels that go in the bottom. These are in addition to the bricks that line the entire box and are a sacrificial piece. I think these might be referred to as kiln shelves (?) but most I see googling don't list all dimensions, or they are too thick (ours are 3/4"). Thicker may last longer, but sacrifices headspace in there. I'd prefer to buy from the OEM as we don't often need parts for these things, but I don't know if it's something that would be better to just buy anywhere. We bought both ovens new and they tend to last pretty well needing an odd part every 10-15 years.

We have two ovens. Newer one made by Paragon in Mesquite Texas which would need a 12"x34" panel. I have gotten help from them in the past so this one might be covered (I've already shot them an email).

The other older oven was made by Schindler Electric in Brownsburg Indiana. This one needs a 9"x18" panel. Is anyone familiar with this company, if they're even still in business? Phone has been disconnected, no website, and street-view still shows their name on the door, but not a substantial looking presence. I'm fairly certain we bought a replacement thermocouple from them a couple years ago, but I seem to remember them being a smaller one or two guy operation.

We could use smaller bricks to make up the floor, but a solid piece is preferred as it reduces the risk of it falling out when parts and trays are drug out of the oven. Also just trying to replace what's there and not re-invent it if possible. If they aren't overly expensive, I'll likely buy a couple of each panel so we have them for later.

We use these ovens for heat treating parts, annealing and thermal stress relieving, and for oil-blacking mild steel parts. Most parts go in and out in some trays we've made, and we're thinking about adding some loose stainless rollers to the back of the trays to reduce wear on the oven and to make inserting and removing heavier pieces easier.

Not sure if your oven might have mullite panels on the floor. If so, I can tell you from recent experience that mullite is easy to cut with a diamond tile saw.
I had a couple of over-sized pieces that I trimmed down in just a few minutes with a saw I rented locally. I was surprised as I expected it to maybe be slow going as mullite is so dense. Nope. Easy peasy.

Any of the big ceramic supply stores such as Sheffield Pottery can supply a variety of shelves, mullite and alumina shelves are the cheapest and least durable, silicon carbide are very durable, a little thinner and still easy to cut with a diamond tile saw, the advancer shelves are the most durable and thinnest but I don’t know about cutting them.
For other refractory supplies, Able Refractory Supply, http://www.ablerefractory.com/ is much cheaper, than the pottery ceramic supply places and very easy to work with.
