Attic Ladder Selector

While Werner offers a large selection of attic ladders in various lengths and material, they are designed to fit standard rough openings of: 22-1/2“ x 54”, 25” x 54”, 25-1/2” x 64” and 30” x 54”.

The Energy Seal attic ladder includes insulation within the structure of the door, and a built-in jamb and weatherstripping around the inside of the frame, which creates a tight seal and greatly reduces the amount of air that flows between your attic and your living space.

No. There are too many differences between the Energy Seal product and our traditional attic ladders in the product structure to be able to convert. However, Werner does sell an installation and trim kit (SKU AC59), which includes weatherstripping to add to the frame of your existing attic ladder.

Due to various opening sizes and finishes, a door is not included with this ladder. To make a door, use ¾” cabinet grade plywood, cut 1/8” smaller than the wood door frame opening. Screw the hinges (included) to one edge of the door and then attach them to the frame of your opening. To install the latch and location bracket, follow Step 9-10 in the instruction manual.

Werner recommends using 1 x 3 boards to create a frame within your opening, and then 1 x 2 boards (recessed the thickness of your door) for the jamb. You may also choose to install trim around your opening on the ceiling.

This ladder uses a combination of angle from the opening, and pre-determined adjustments on the slide-down sections to control the length. This ladder works with floor-to-attic floor heights from 7’ to 9’ 10”. Each section of the ladder has 2 different positions to catch onto the other section, so you might need to experiment to find the best height for your attic. During the installation process, depending on your floor-to-floor height, you might have needed to install additional stops. Step 2 in the instruction manual provides detail on when these are needed. If you added them and should not have (ie, your ladder is too short or at too steep of an angle), you can remove them. The correct angle from the floor is 68 to 80 degrees.

A ¾” wood floor, a minimum of 27” deep by the full width of your opening is required to attach the assist arm.

Most likely, the assist arm is oriented the wrong way. When the arm is mounted to the attic floor, the arm should be pointing away from the ladder and opening. If you did not do this, un-attach the arm from the ladder, unscrew the arm from the floor, and reverse it.

To extend the ladder, place the assist pole over one of the bottom rung of the rear section of the ladder and pull it down towards you until the top stops hit the hinge guides. Retract both right-hand side catches and rotate both upwards into the locked open position. Then retract one of the left-hand catches, while supporting the frame of the ladder. Lower the frame slowly until that catch engages again. Retract the other catch on the left-hand side and lower the middle frame until the second catch engages. The feet should rest firmly on the floor, and the ladder should be at a 68 to 80 degree angle. Once the ladder is extended, rotate both right-hand side catches downward to unlock and release them so they lock into the other ladder sections.

Before installing, verify the dimensions of the area where you intend to install this ladder vs. the dimensions on the packaging of the item you bought. If your attic ladder will not open fully or extend completely to the ground, do not modify it for use.

Measure the installed frame from corner to corner (diagonally). If the two measurements are within 1/8”, your frame is square. If your frame is not square, insert shims to square it. From inside the attic, check for obstructions when the door is closed-check shims, installation, cords, to make sure nothing is interfering with the door shutting properly. Check the springs (or struts) of your ladder and make sure they are working correctly.

Werner sells a replacement foot (item number 36-83 for AL2210’s and 36-98 for AH2210/AH2510) that goes 3” farther up the rail of the ladder than the one that comes with the ladder. If it is a minor cutting error, this can correct it.

No. Check with your local building code if that is what’s driving this question. Chances are, you need a product that protects against burn THROUGH, which means you need to add gypsum to your attic door to stop flames from burning through. Merely stopping the spread of flames (as products that meet the E84 standard do) will potentially not meet code in your area.
