 A Flexible Lid is one that is very movable and bendy. You can identify if you have a flexible lid by raising the lid from the corner. The entire lid will not raise. The lid will droop towards the center of the dumpster. These lids are not sturdy.

A Solid Lid is one that is more sturdy. You can identify if you have a solid lid by raising the lid from the corner. If the entire lid raises remaining mostly straight and horizontal then it is a solid lid. These lids are not super bendy or flexible.

First it is important to measure the correct top rail. You will want to measure the top rail of the side wall of your dumpster. (This is where the Kleen Opener will be mounted.) Measure across the top rail as shown in the picture.

Measure in INCHES. Be as accurate as possible.

To measure the length of your lid start with the lid closed. Measure starting from the back hinge of the dumpster. Measure flat down the lid to the front edge. (Measure to the front edge of the lid, not the front edge of the dumpster.)

Measure in INCHES.

Metal Angled Inner Dumpsters have a metal body, meaning the main structure and walls of the dumpster are made of metal (this is separate from the material of the lid). Additionally, these dumpsters have an angle from the top rail to the inner wall of the dumpster.

To identify the Angled Inner Top Rail, look at either the left side or right side wall of the dumpster from the inside. You will see that the Inner Top Side Rail of the dumpster angles down into the inner wall of the dumpster before the wall runs flat down the base.

Metal Flat Dumpsters have a metal body and have an Inner Metal Liner welded to the inner Flat wall of the Dumpster; where the welded metal liner is just below the Top Side Rail of the Dumpster.

To identify the Metal Flat with Lower Inner Liner, look at either the left side or right-side wall of the dumpster from the inside. You will see just below the top side rail of the dumpster a Metal Liner that runs flat and parallel with the inner wall of the dumpster.

Some Metal Flat Dumpsters with a metal body have Flat Inner Side without a Metal Liner for the first 2 to 3 inches below the Top Side Rail of the Dumpster.

To identify the Metal Flat Dumpster without a Metal Liner, look at either the left side or right-side wall of the dumpster from the inside. You will see just below the top side rail of the dumpster does not have a Metal Liner for at least 2 to 3 inches below the Top Side Rail of the Dumpster’s Inner Wall.

Some Metal Flat Dumpsters with a metal body have Flat Inner Side with a Metal Liner that is welded to the Top Rail and can extend anywhere from a ¼ inch to 1 inch above the side Top Rail of the Dumpster.

To identify the Metal Flat Dumpster with a Raised Metal Liner, look at either the left side or right-side wall of the dumpster from the inside. You will see a Raised Metal Liner that extends above the Dumpster’s Top Side Rail anywhere from ¼ inch to 1 inch.

Some Metal Flat Dumpsters with a metal body have a Flat Extended Lip that extends out as part of the Dumpster’s Top Side Rail anywhere from 1 inch to 3 inches as part of the Top Rail of the Dumpster.

To identify the Metal Flat Dumpster with an Extended Lip, look at either the left side or right-side wall of the dumpster from the inside. You will see the Top Side Rail extends anywhere from 1 inch to 3 inches and has a Flat under-side that is perpendicular to the Inner Side Wall of the Dumpster’s Body.

Plastic Flat Inner is for dumpsters with a plastic body, meaning the main structure and walls of the dumpster are made of plastic (this is separate from the material of the lid).
The determining factor for this mount is less about what the inner wall of the dumpster looks like (unlike our other mounts) and more about the quality of the plastic.

These plastic dumpsters are made more rigid and solid. The side walls tend to run perpendicular to the back wall (where the lid is mounted). The side walls and Side Top Rail of these Plastic Dumpsters are most likely to remain straight and not bow (as they tend to do for Mount #7). If you have a plastic dumpster with a Side Top Rail from 2 to 5 inches wide, then most likely this is your dumpster type.

Dumpsters with a Plastic Inner Lip have a plastic body, meaning the main structure and walls of the dumpster are made of plastic (this is separate from the material of the lid). Additionally, these dumpsters have a lip or edge that sticks out on the inner wall.

To identify a Dumpster with a Inner lip, look at either the left side or right-side wall of the dumpster from the inside. A couple of inches down from the top side rail of the dumpster there is a lip that sticks out, before returning to the flat inner wall; as shown in the image.

Additionally, these dumpsters are usually made from a more pliable plastic. This can be seen when the side walls bow (curve out) either due to overloading or the elements. Therefore, the Kleen Opener mounting bracket for this type of dumpster is made with some additional components: a supporting angle bracket and a spacer. These two pieces are necessary for mounting the Kleen Opener bracket securely to the plastic top rail and allowing the proper spacing for the arm to open and close without hitting the wall.
