Made the gap on my hatchling rack too big...

[Kodieh]

Any one have any inventive ideas to fix it that don't involve disassembly and reassembly?

The gap is the "tick" between 1/4th inch and 1/8th inch, is that actually too much?

Weather strip around the top of the top of the tub????

Use lids?

Use lids?

Its a little tight with the lids on. I could sand the lids down a bit.

Weather stripping might work if it's varied in size and solid.

Sheet of plastic glued onto the underside of the shelf above?

When my big rack started getting tight on the bottom tub I took the base off and put some strips of steel on the base of the carcass before putting it back on ( I did need to use longer screws though ).

10/10 should just take it apart and redo it. :p

just use wood of the right thickness and cut it to fit underneath the tubs. dont fix them in place, just put them under there.

of course that depends on how the heating is set up. that would not work in most cases. but you can reduce the height from the top or from the bottom. so the same wood pieces could be put in over the tubs. loose or fixed in place.

since you want to reduce the height by just a bit, taking it apart and putting it back together seems to be the very last option. it just calls for a hack that involves adding the right material of the right thickness.

maybe you can use material that has the benfit of adding thermal insulation. i just said wood because its the obvious thing. but you can also get panels of material that have styrofoam-like stuff in the middle and coated cardboard on the surfaces. i dont think plastic is a good choice, because unless its foamed somehow like styrofoam, thermal conductivity is really high for some plastics. i would look for a composite material with low thermal conductivity, a good insulator, second choice would be wood. there is no third choice because wood will do the job.

now where are the heat sources located and how are they attached?

Get something to wedge the tub a little higher.
Like a thin panel, window shims, or something to bump it up.

How small do you want the gap. If you screw 1/8" board, plastic or, metal in that should leave you with 1/16" gap. You will want to countersink the screws so the tubs don't catch though.
