Hi,

I wondered if you could help me ID this plastic piece and others like it placed on the corners of the back of the drawer doors. The piece is under 3 cm. long and a bit over 1 cm. on the top. The pieces aren't supposed to move, but because the drawer is so old, they can be spun around so they need to be replaced.

Your help is appreciated.

Thanks,
Dan

Hey Dan. Is this a drawer spacer? If so, see if the 32-334, 32-339, 32-350 or 32-352B match up. Look over the dimensions and see what you think.
