Eye Lags & Eye Lag Poles. We handle a variety of eye lags for both steel and wood including stainless steel and eye lags for thicker metal. Suspending from wood beams and steel deck can easily be accomplished from the floor with either the Lagmaster Plus or the Purlin Master. So what's the difference between the Lamgaster Plus and Purlin Master? Essentially they are same basic tool, the difference is in the plug ins.
