>>Hello. I have just finished building my new BP rack and I need to install the Flexwatt. I want to use the 11" wide, but the tubs I've got only have a space of about 9 1/2" between the little plastic "feet" on the tub. This means if I use the 11", the tub feet would most likely rub a little on the Flexwatt. Is this bad? Should I not go this route? Or would it be ok for the feet to rub a little. Please let me know. Thanks a lot.
Yes, the feet will rub on the heat tape. If the clearance between shelves is tight, they will also tend to catch the edge of the heat tape as you slide them in and out of the rack. You can use aluminum foil tape, as clints suggests, to hold the tape in place. In my experience, this will work for maybe 9-12 months before the heat tape starts getting torn up.
If you scroll down a bit, you'll see the "One More Question About Melamine or Plywood" thread, where Clint and I hashed this out recently. I won't bother to repeat the whole discussion again.
