What's With the Giant Glas-Col Cord Plugs?

careysub - 11-2-2016 at 22:43

I have acquired three used Glas-col heating mantles, without cords. I have purchased three Glas-col heating mantle cords on eBay. They all feature a plug interface that is a good bit larger than my heating mantles.

I have never seen any discussion on heating mantle cords, and the existence of two sizes. Certainly no eBay vendor of mantles or cords says "small" or "large" or similar.

Anyone need large-size Glas-col cords?

Are they possibly meant for more amps? If so, you should be able to switch out the plugs for a compatible type relatively easily, considering you know how many the mantles need...
Some photos might help?

Just in case you don't know, heating mantles are designed to plug into a heating mantle controller, not the mains.

Edit, (the ones without integral controllers)

Mantles of different eras have different plugs. For this reason, ebay mantles without cords should be avoided.

Does the larger one have a center ground fitting? If so, they are for larger, grounded units, mostly the ones with aluminum hard shells. The smaller, flexible fiberglass units have 2 prong cords and plugs. If your plug looks like it would fit this:

then it is a 3 prong cord.

I have some of the 2 prong cords that I could trade for 3 prong ones, as I need a couple of the 3 prong ones.

I intend to plug it into a variac, which I have, if that is what you mean.

There is a central circular split copper looking thingy.

Then that is the grounded one for the hard cased mantles. I'm happy to swap you for what you need, which is the 2 prong one, with two arcs to plug into, one is smaller than the other, right? Just PM me if you wish.
