If you have ever ordered signs and they did not fit into your old frames or on to your posts correctly, you learned the hard way about the importance of correct measurement and placement of holes on a sign panel. Different sign companies use different hole patterns so if you are using sign panels from one company and frames or posts from another company, it is very important to know how to determine the hole patterns your signs require.
If you follow these steps, you should be able to determine the correct hole pattern for your signs.
1. Position There is usually 3 positions that holes are on a sign; top, bottom, and on the side of the sign. For each position determine how many holes are needed. Normally 2 holes are needed on top and 2 holes are needed on the bottom. Some signs need side holes and others do not.
2. Quantity Most signs will need 2 holes at the top and 2 at the bottom. Some may require more.
3. Hole Size For signs that hang from a post, the standard size is 3/8 (technically 11/32 inch holes with a 3/8 inch grommet). For signs that go into an angle iron frame or fasten to the strap of a rod frame the standard size is 1/4 inch.
4. Location of the holes is important. By location, I am referring to whether the holes are centered, corner holes, or a single hole. Most signs have 2 holes centered at the top and the bottom.
5. Distance between the holes is very important. The measurement needs to be done from the center of the right hole to the center of the left hole, not the edge of the holes. A common distance between holes is 17 inches on the top and 14 ½ inches on the bottom. If you have a post with hanging hardware, it is important to measure the distance between the hardware exactly. By doing this measurement correctly, your sign panel will hang straight down on the hardware instead of veering either inward or outward because the distance between the holes on the sign is different than how the hardware hangs. If you are planning to hang riders below your sign, make sure the bottom holes of your sign match up with your riders.
6. Edge Distance For frames this measurement is especially important. Again, the measurement needs to be done from the center of the hole to the edge of the sign to determine the correct edge distance. Do not measure from the edge of the hole. A common edge distance for top hanging holes is 1/2 inch and for bottom holes 3/8 inch.
7. Grommets Last, let your sign supplier know if you require grommets on any or all of the holes of your sign.
If you follow these steps, you and your sign supplier will be speaking the same language and your signs will be ordered to fit your frames and post.
