150 (B C D) 
 
Our inline internal tube connector is a galvanised straight clamp fitting for connecting rails of the same size.
 
This fitting can only be used for 3.25mm wall thickness tube (1”, 1 1/4” & 1 1/2” BS EN 10255, formerly BS 1387, medium weight) and must not be used as a load bearing joint, particularly for tensile loads.
 
Kite clamp fitting #149, which has superior load characteristics, may sometimes be used as an alternative.
 
We also supply Galvanised tubes. To buy our 3.2m galvanised tube, click here. To buy our 6m galvanised tube, click here.
