The specialists
Wait to buy these clamps until you have a specific need for them.
Band (or strap) clamp ($20–$35 for 6–23')
Wrap its webbed strap around a glue-up to hold corners together, such as when assembling a box or drawer. Some have blocks with pivoting jaws that protect delicate mitered corners and can accommodate corners other than 90° [Photo M]. The blocks also lift the strap off the workpiece so the strap doesn’t get glued in place or fouled by squeeze-out. Tighten a screw or a ratcheting mechanism to apply pressure.
Corner clamps ($15)
These often serve as a much-needed third hand, aligning perpendicular pieces as you twist the handle to apply clamping pressure. If you see frame making in your future, a set of four makes life much easier [Photo N].
C-clamps ($5–$20)
For the money, nothing beats C-clamps for applying pressure [Photo O]. The crossbar in the screw handle, the hefty threads, and the beefy iron body make these clamps overkill for most jobs. However, the long threaded rod provides a large capacity (after much spinning of the screw).
