Install Underside Trim or Supports

What happens here

Some modular pergola systems include additional trim pieces or smaller support beams that attach to the underside of the main top beams. Position these components precisely and secure them using an impact driver and appropriate screws. The video shows a worker fastening a piece from underneath, driving screws upwards into an existing beam. This can be for a decorative fascia, a lower support ledger, or to complete a specific profile of the beam system. Ensure all connections are tight and flush.

Goal: This step involves adding additional structural or decorative elements underneath the main beams, often to enhance aesthetics or provide extra support, by fastening them with an impact driver.
