where to buy plastic ceal for bottom of kitchen cabinets?

After a little research I think it might be called an END CAP????

Think you might find seal would be a better spelling as well.

IKEA plinth boards (aka kickboards) are packaged with the seal & wordless instructions, so sorry can't help with the name ;-)

It might just be possible to obtain a seal ex IKEA. If, as most likely, it isn't on the shelves then call in on the kitchen dept & ask them if they can order one for you. On another kitchen item they were able to explode the components of a package on screen & order an individual item for me. You may need a sob spiel 'damaged while fitting' etc, & you may need one of the local experts on their computer system.

Otherwise look in yellow pages for kitchen component wholsesalers. A few of the regular kitchen installers also have substantial parts operation & supply other installers.
