This string ladder is for 1/2" micro-mini blinds. Micro mini blinds are marketed as 1/2" wide slats, but in reality, the slats are usually about 5/8" wide.

This ladder may work for Pella in between the glass Slimshade blinds with 15mm aluminum slats, but carefully measure the spacing between the slats before ordering. It may also work for slats that measure 16mm.

The spacing from the top of one slat to the top of the next slat is 12mm, which is .47" or about 15/32".
