The tolerances specified for the outside diameter of the round construction tubings comply with the requirements for split mono-block connector clamps. Inch tubing complies with EN 754 and EN 755. Metric tubing complies with DIN 2391, DIN 2395 and DIN 2462.
Two-piece connector clamps obviously allow larger tolerances on round and square construction tubings.
Other lengths of tubing, in 1 in. increments up to 96 in., also available upon request.
For end plugs, see WN 991 (inch size) and GN 991 (metric size).
