What this is
A 48" parallel clamp — considerably longer than the 24" clamps covered in our parallel clamps comparison, aimed at wide panel glue-ups, large casework, or door assembly where a 24" clamp simply doesn’t reach across the work.

Rockler 48" Parallel Bar Clamp
Rockler also sells this parallel-jaw design in 24" and 40" lengths, all sharing the same jaw and pad construction.
View Price on AmazonWho this is for
Wide panel edge-joining, casework assembly, drawer boxes, and raised panel doors where 48" of parallel-jaw reach is genuinely needed — a 24" clamp won’t span work this wide.
Who this isn’t for
Standard-width panel glue-ups where a 24" clamp already covers the span — the Bessey K Body REVO (1,700 lb) and Jorgensen 8024 (1,500 lb) in our parallel clamps comparison both rate higher force at that shorter length, and a shorter clamp is lighter to handle for smaller work.
Bottom line
Manufacturer-sourced specs, not a hands-on test. On paper this fills a length gap none of the 24" parallel clamps already on the site cover, at the cost of a lower force rating and real added weight (9.70 lb) per clamp. Rockler 48" Parallel Bar Clamp if your glue-ups regularly need 48" of parallel-jaw reach.
