When to choose it

Choose the 1440-AC when you can approach the ring in line with the joint and want a closing spring to bias the jaws together while you position it. The forged steel pliers have grooved jaws and straight vinyl-covered handles. The straight shape is easiest to evaluate with the seat and attachment point in their working positions.

If the surrounding frame makes a straight approach awkward, compare the bent 1440-BC, which keeps a closing spring. If your approach works but you want both jaw movements under your hand, compare the straight 1440-A with no spring. Check the ring separately before buying either version.
