The fischer beam clamp TKR is a tensioning clamp for the fixing of mounting rails to steel girders. The TKR is attached to girders with different widths on both sides. Drilling and welding is not necessary, which saves time. fischer offers the TKR in three sizes from a height of 21 mm to a height of 124 mm. The galvanised zinc design is suitable for installations in buildings, the hot-dip galvanised or zinc flake surface coating and stainless steel designs are suitable for installations outside and in highly corrosive environments.
