144 - Side Support (Vertical Base)
A palm-type fitting, often used to attach guardrail uprights to walls, staircases and ramps.
In standard form, the tube cannot pass through the bottom of the fitting, although the fitting may be modified to accommodate this at extra cost.
N.B. Access to one of the fixing holes is limited and may restrict the length and type of fixing that may be used. Dependent on load requirements, type 145 may sometimes be used as an alternative.
