Blum tandem plus guides need how much room on the sides so if you had a frameless box 20 inches wide with 3/4 sides totaling 1 1/2 which would be a 18 1/2 opening thanks
We recommend the BLUM 563H undermount drawer glide.
Opening Width - Deduct 3/8" from the opening width.
Opening Height - Deduct 3/4" from the opening height then round down to the closest 1/2"
