Type 21 - 90° Side Outlet Tee
Most frequently paired with Type 20
to give a 90° corner joint for the
middle rail of safety railing and other
rectangular structures.
A21-A26 - Split Two Socket Cross/90° Side Outlet Tee
This fitting performs the same function
as either Type 21 or Type 26,
but because of its unique hinge pin
system, it can be added to an existing
tubular assembly.
Type 327 - Three Socket Custom Tee
Used for safety railing on slopes
between 0° and 45°, between the top
rail and an intermediate upright which
is required to remain vertical.
