3 Sided Exposure - Irregular Columns With Tracking Attachment

Recommended Panel Configuration & Measuring

If you have irregularly-shaped columns, you have one choice, an Inside Hang, where panels take a path INSIDE your columns.

Projects with Irregular-shaped columns are generally 4 panel configurations for ease of use and natural looking swags. Panels 1 starts at the house and ends somewhere between H1 & H2. Panel 2 picks up where panel 1 left off, straddles the first corner column at H2 and ends somewhere along side 2. Continue similarly with panels 3 & 4 till you are back at the house on side 3.

Panel Configuration Example

Measurement Tips

  • Measure the exposed widths of both sides ALONG the path your tracking will take WITHOUT ANY OVERLAP (which we will adjust for momentarily).
  • Measure heights at all 4 corners from underside of track mounting surface to floor. The 4 heights could be different and you cannot assume all heights are the same.
  • If for some reason you don’t have a good under-mounting surface, remember you can make one by side-mounting a 2″x2″ wood strip, then under-mounting track to the wood strip.
  • We divide your project into 4 individual panels, 2 of which straddle the outer corners.
  • 3 Panel breaks with magnetic doorways are wherever you like on each of the 3 sides.
  • IMPORTANT: Sum width of all sides = Sum of all panel widths.

The configuration diagrams below demonstrate two examples from a top view using marine snaps, magnetic doorways, and stucco strips. Watch the video to get an overview on how to measure and some ideas for your panel configuration.

Panel Adjustments (Or Use Calculator Below)

Once you have your panel configuration, there are a few panel adjustments to make for each panel. The sum width of all your panels needs to be wider than your actual exposure for overlapping magnetic doors or overlapping a structural surface (like a wall or column) and a little more so that you can have a relaxed fit. Use our panel calculator below to help with your calculations.

WIDTH ADJUSTMENTS (or use calculator below)

  • Automatically add 2-inches per panel regardless of width, then
  • Add another 1-inch per panel for EACH edge that will snap to some surface
  • Subtract 1-in for EACH edge connecting a Stucco Strip, and ignore width of stucco strip
  • For Tracking Attachment: Add another 1-in per 10ft of panel width for relaxed fit


  • NO height adjustments necessary for tracking. The 1-inch drop in the track will automatically give you a 1-inch overlap with the floor.
  • Measuring is done from the bottom of the track mounting surface to the floor.

Simple Panel Adjustment Calculator (if all heights are the same)

This simple panel calculator will make your panel adjustments for each panel, one at a time!

Use this calculator by entering the 5 pieces of information required to adjust your panels. Repeat for each panel larger than a stucco strip.

NOTE: If the difference between all 4 heights is less than 1.5-inches, just use the tallest of the 4 heights. If the heights differs more than 1.5-inches, call in your order because we will need to taper the slope.
