burnt tubs?

[Stewart_Reptiles]

Hi guys i have a home built snake rack using heat tape and tubs sterlite and flexwatt. but i noticed today that the tubs are melting where they are in contact with the tape. Can anyone recommend better tubs the heat temps are on par and i am using a thermostat

What kind and where is the probe?

A thermostat controls temps while a thermometer reads them so the question is do you have one of both?

If your tubs are melting this means either your T-stat does not work or allows heat spike, and in that case if the only thing that happens is your tubs being melted you will be lucky.

If your tubs are melting this means your animals are probably burnt if they were on that side.

Nothing to do with the tubs!
