Used in pairs to form variable angle joints between 90 and 180 degrees.
When calculating cutting lengths for tube, dimension 'E' should be subtracted to give true tube length.

Note: Type 19 fittings are normally used in pairs, but are sold and priced separately outside of the US and Canada.
In the case of type 19-8 and 19-85 these fittings can produce an angle range between 60 and 180 degrees.
