Photo Eyes or Beams are “non-contact” devices that operate by shooting a beam of light across the gate opening.

One of the most important things in a gate’s design is a cross-brace in the structure, starting from top corner opposite the hinges (free-swinging side of the gate), pointing downward to the lower hinged side of the gate. It acts like a giant shelf bracket that will hold the gate structure at a 90-degree angle to the post on which it’s mounted. It is the simple physics of the triangle shape that makes this work.

If you ensure that the cross-brace is angled greater than degrees from the base of the gate, the door will support itself, and last much longer. It is important to note that an angle less than degrees will render the cross-brace ineffective, because the cro. See full list on fix. Depending on where you live, the number-one thing to check before installing the posts is your area’s typical depth of frost. You want to ensure that your posts are set into concrete below where the indicated frost level is.

This provides a solid anchor into the ground. If frost is not a factor in your region, a depth of inches should be enough to support a gate. To install the posts, you’ll need to dig a hole between and inches deep. The hole should be about inches wider than the post. For example, if the post is inches wide, the hole should be inches wide.

Pour a few inches of gravel in the hole, which will help with drainage. Drop the post into the hole. Fill in around the post with concrete, while keeping the post plumb with a level. This is easier with a second person. Make any final adjustments to the post to ensure it is straight up and down.

It is a bonus if you can make the posts long enough to install a header over the gate opening, with enough clearance to. In most regions, there are two basic lumber choices: pressure-treated lumber (PT) and non-pressure treated(NPT). Pressure treating is the process of adding chemical preservatives to the woo to resist rot and bugs.

Both PT and NPT are readily available, although the species available can change, depending on your area. When choosing a NPT lumber, because there are no added preservatives, you would want to select a wood that has natural anti-rot properties. The chart below shows North American species that have these properties.

PT lumber, often spruce, is cheaper than most NPT woods, and has a lower natural resistance to rot or bugs. As mentioned above, it is treated with chemicals to give it those properties. Recent environmental regulations have changed the chemical compounds used in PT, so ensure you are using approved fasteners with a rating for ACQ (alkaline copper quaternary, a wood preservative), since the wrong type of fasteners can rot when in contact with the compounds in.
