Lally Columns

A Lally column is a round thin-walled structural steel column filled with concrete, and oriented vertically to provide support to beams or timbers stretching over long spans.

Lally Lock System:

The Lally Lock System is made up of three components:

1. The new Lally Lock Column: This column has the same
   strength as our old style but has an embedded fastening unit in
   the top of the column. The embedded fastening unit is made up
   of a 6″ anchoring bolt threaded into a 1 1/4″ coupling nut,
   which is embedded in the concrete. A welded steel disc finishes
   the top of the column.
2. The Lally Lock Cap Plates: These plates are designed to
   accept a 1/2″ bolt that is screwed into the coupling nut inside
   the embedded fastening unit.
3. The Lally Lock Base Plates: The adjustable base set allows
   for 3″ adjustment and is fastened to the column with concrete
   screws. The base plates with the ring prevents lateral
   displacement. The Lally Lock base plate is connected to the
   column with a concrete screw.
