All you need to know is:   D  L  O

  • Definition:  DLO stands for Daylight Opening Measurement.  The space from inside to inside of two objects; typically 2 of our Gate Posts.  OR... two existing structures (house, building, wall, column) or one of our posts and an existing structure.  Different hinges are needed sometimes for different applications.  Wide and larger gates require you to upgrade to our Heavy Duty Gate Hinges (gate operator friendly) or the Industrial Self Closing Gate hinge (not gate operator friendly). 

  • Bonus: You don't have to worry about how much spacing is needed based upon the hinge options.  We will  do that and fabricate the gate and the hinges in your order to fit the DLO measurement you give to us.  All you have to do is provide us with the correct measurement.  For example, let's say you were going to install a single swing gate between two walls that measured 68 1/2 inches... wall to wall.  And, you wanted to flush mount two - 2x2 Gate Posts (Blank) to each wall.  Well, you would subtract 4 inches from 68 1/2 and that would leave you 64 1/2 inches as your DLO. 

  • Ordering:  All you need to do now is order and pay for a 72 inch wide gate and during checkout, write in the Customer Notes text box:  "DLO = 64 1/2 inches".  That's it!  It doesn't matter if you use the standard hinges OR if you upgrade to our self closing hinges; WE will accommodate the right spacing based upon your DLO.

Daylight Opening (DLO)

How to Order:

Locate the gate you would like to order.  Then, select the next gate width WIDER than your opening and add it to your shopping cart.  Example:  If you have a 52 inch wide DLO, order and pay for a 60 inch wide gate.  If you have a 140 inch DLO, order and pay for a 144 inch (12 foot) wide gate. 

Another example.  Because of spacing at your home or business, you only have 22 feet, 2 inches to work with.  You know you need 2 of our 6" x 6" Steel posts for this large, driveway gate, so you can subtract that out, leaving you with a 21 foot DLO.  Well, we don't have 21 foot wide gates listed on this website.  We do, however, have 22 foot wide driveway gates.  Therefore, you order and pay for the 22 foot wide gate (and all it's options if applicable), then during checkout, you'll tell us to fabricate the gate for a 21 foot DLO.  It's that simple.  Our team at the factory will further subtract out the needed spacing for the Heavy Duty Gate Hinges but that's not your concern.

During checkout (Step 3, right before you enter your cc info) notate your specific DLO in the CUSTOMER NOTES text box and complete your purchase. 

Double Check your Order Confirmation Receipt (emailed to you) for the DLO notation -- this confirms your custom width measurement.

It's not uncommon for homeowners to purchase residential aluminum fencing along with commercial or industrial driveway / estate gates.  Single swing gates wider than 6 feet and double swing driveway / estate gates wider than 12 feet will require you to purchase self-closing gate hinges (industrial version) or Heavy Duty Gate Hinges.  Heavy Duty Gate Hinges can only be attached to our large 4" x 4" Gate Posts or an existing structure large enough to support our 4" x 4" hinge plate.  If you will be automating your gate at any time or in the future do not order self-closing hinges because the spring loading mechanism won't work with gate operators.  Our Heavy Duty Gate hinges are perfect (and friendly) for gate automation.
