Bar length is the leverage and it is chosen against what has to be moved rather than the space available. A short bar in a tight position gives very little, and forcing it bends the bar rather than moving the work, which is how a bar is ruined in one use. A bent bar also never levers straight again, which is why it is a single-use mistake.
End profile decides what the bar does once it is in. A flat end slides into a joint and separates two surfaces. A rolled end levers off a fixed surface and gives progressive lift as it turns. A claw end pulls a fixing rather than levering against it. Reading the profile against the joint rather than the material is what settles which end is needed.
Most jobs use more than one profile, which is why sets exist at 3 and 4 pieces rather than bars only being sold singly. A set also covers a range of lengths so the same job can be started with a long bar and finished with a short one. Sets also arrive with the guards fitted rather than as an accessory bought afterwards.
A hand guard matters where the bar may slip. Under load a bar that releases suddenly takes the hand with it into whatever is behind, and the guard is what stops that. Lengths here run 200mm, 300mm, 450mm and 600mm. Send the job to 07754288583 on WhatsApp. Rolling head bars also work in a confined position where a straight bar cannot be angled.
