Base Plates

Once connectivity is chosen for the top of the column and beam, determining the base is easy. The Lally Lock Base Plate is designed to connect the plate into the column with a concrete screw through the middle of the plate. Other options involve welding either the standard or beam plate to the column. Using a beam plate is better for larger weight distribution.

While the Lally Lock Base Plate is simple, the Adjustable Base Set offers a lot more. This base set allows up to 3” adjustability, making it easier to install. When installed correctly, the adjustable plate helps with self-leveling and no shimming is involved. This helps with installing saddle plates and is particularly useful for one person to install. Instead of one person on either end of the column, the adjustable base allows for the cap plate to be installed first then pairing the base and bearing plate set together. Installers can pour a 4” slab floor around the adjustable base set or encase a concrete footing between the bearing and base plate with a grout of at least 3,000 psi filling in the gap. The adjustable base set is a great choice for either new construction or renovations.

Beam Plate with Ring

Similar to the Springfield plate. This plate has a welded ring that encompasses the top or base of a 3 ½” or 4” column. It is also similar to the lally lock beam plate as it has the same hole configurations. However, this plate has to be welded to the column. It comes in different size plates to fit different beams: 3 1/8” x 8” x ¼” for 2 2x’s, 3 5/8” x 8” x ¼” for 2 LVL, 4 5/8” x 8” x ¼” for 3 2x’s, 5 3/8” x 8” x ¼” for 3 LVL, 6 1/8” x 8” x ¼” for 4 2x’s, and 7 1/8” x 8” x ¼” for 4 LVL. These plates are packaged with GRK screws.
