## Abstract

Methods and devices for making a plate clip for securing a plate to a channel letter including: selecting a size of the plate clip and cutting a clip form; selecting a plurality of fold positions of the plate clip based on a panel size, the panel size being based on a plate thickness and a width of a rib; cutting the clip form to form a plurality of barbs; and folding the clip form at the plurality of fold positions to form the plate clip and expose the plurality of barbs.

## Claims

### Claim 1

A device for securing a plate to a channel letter, the device comprising:
a top gap having a top gap width and a top gap depth and sized to receive a rib, the rib being adhered to a profile used to make a channel letter;
a bottom gap oriented opposite to the top gap and sized to receive the plate of the channel letter;
a first plurality of barbs, each barb of the first plurality of barbs being oriented toward an inside of the top gap and configured to fit between the rib and the profile; and
a second plurality of barbs, each barb of the second plurality of barbs oriented toward an inside of the bottom gap and configured to penetrate a surface of the plate.

### Claim 2 (depends on 1)

The device of claim 1, wherein the plate is a bottom plate.

### Claim 3 (depends on 1)

The device of claim 1, wherein the top gap width is substantially equal to a thickness of the rib.

### Claim 4 (depends on 1)

The device of claim 1, wherein the top gap depth is substantially equal to a width of the rib.

### Claim 5 (depends on 1)

The device of claim 1, wherein the bottom gap includes a width substantially equal to a thickness of the plate.
