Cross clamp 2-part, with 4 steel screws 10 x 25 mm; A 1 1/2" x B 1 1/2"; length: X=140 mm and Y=140 mm
Design of the clamp: hot-dip galvanized all-steel design
The inch specifications of the pipe diameters (outside diameter) are not to be equated with the inch (25.4 mm).
Previously, the dimensions referred to the inner diameter of the pipes and the outer diameters were correspondingly larger (approx. 33 mm for 1 inch). Over the decades, new production processes and better steel qualities have made it possible to produce thinner-walled tubes. As tools (taps, etc.) and accessories were already available for the "old", larger outside diameters, the outside diameter was retained and the inside diameter of the tubes was increased.
That is why "inch" tube dimensions are now defined metrically. Please inform yourself before buying which clamp / pipe connector fits your needs.
Please refer to the following table:
Tube size in inch = outside diameter in mm
Tube 1/2" = Ø 21.3 mm
Tube 3/4" = Ø 26.9 mm
Tube 1" = Ø 33.7 mm
Tube 1 1/4" = Ø 42.4 mm
Tube 1 1/2" = Ø 48.3 mm
Tube 2" = Ø 60.3 mm
Tube 2 1/2" = Ø 76.1 mm
Tube 3" = Ø 88.9 mm
