- Page 9 Model LPA Application LPA The model LPA has a lock open and lock closed feature built into its design. The LPA has an auxiliary lock. The LPA clamp is recommend- ed for turning of a single steel plate from horizontal to vertical to hori- zontal through a hundred and eighty degree arc.
- Page 10 WARNING: When turning a plate from horizontal to vertical, the operator must position the clamp at the start of the turning opera- tion so that the lock handle is on the topside of the plate when the plate is in the horizontal position. It should be noted at the finish of a 180 degree turn that the lock handle will be on the underside of the plate and therefore sufficient clearance under the plate should be allowed for the lock to be disengaged.
