I’m buying your BRIXWELL SDCD38BN-CCP36 U-channel for a fixed 3/8-inch tempered shower panel. Which setting-block size and quantity should I order, compatible with the glazing silicone you recommend?

For a 3/8" glass panel, use 1/4" W × 1/8" H × 2" L (or 3" L) neoprene/silicone setting blocks. Space 2 blocks along the bottom channel (placed at bottom quarter points, roughly 2–4 inches from each bottom corner) to cushion the glass and maintain proper clearance for mold-resistant 100% neutral-cure silicone sealant (such as CRL 33S or DOWSIL 999A).
