NFK stocks a range of setting blocks and packers - essential consumables for professional glazing and window installation, used to support and position glass correctly within frames, level and align window and door frames within openings, and prevent direct glass-to-frame contact that can cause stress, cracking, and seal failure.

Clear Setting Blocks - pre-cut clear plastic setting blocks available in thicknesses from 1mm, used to support and position glass panels within rebates. The clear material is discreet and well-suited to frameless and architectural glazing applications where aesthetics matter.

Horseshoe Packers - available in 75mm and 90mm widths and thicknesses from 1mm to 10mm - are used to level, align, and plumb window and door frames within openings. The horseshoe shape allows them to slide around fixings without removal, saving time on installation.

Rubber Setting Block Strip — a flexible, continuous-roll alternative to pre-cut blocks, available in trade and bulk roll lengths. Rubber setting block strip absorbs vibration, evenly distributes glass weight, and can be cut to the exact length required for each application - ideal for high-volume production glazing environments.
