Frequently Asked Questions About Attic Ladders

Do you offer custom attic ladders with various rough openings?
While Werner Co. offers a large selection of attic ladders in various lengths and material, they are designed to fit standard rough openings of: 22.5 x 54 inches (57 x 137 cm), 25 x 54 inches (63.5 x 137 cm), 25.5 x 64 inches (64.8 x 162.6 cm), and 30 x 54 inches (76.2 x 137 cm).

Traditional Attic Ladders

How can I be sure I have the right ladder for my space?
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.
I have an attic ladder installed and the door won’t close/seal completely — how do I fix it?
Measure the installed frame from corner to corner (diagonally). If the two measurements are within 1/8 inch (0.3 cm) 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
I cut my aluminum attic stair too short to touch the floor with the foot attached — is there any fix?
Werner sells a replacement foot (item number 36-83 for AL2210CA’s and 36-98 for AH2210CA / AH2510CA) that goes 3 inches (7.6 cm) 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.
Does Werner sell fire-retardant doors?
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.


There’s no door included with this. How do I get one?
Due to various opening sizes and finishes, a door is not included with this ladder. To make a door, use 3/4 inch (1.9 cm) cabinet grade plywood, cut 1/8 inch (0.3 cm) 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.
I don’t have a finished floor in my attic. How do I mount the arm?
A 3/4 inch (1.9 cm) wood floor, a minimum of 27 inch (68.5 cm) deep by the full width of your opening is required to attach the assist arm.
How do I finish my opening?
Werner recommends using 1 x 3 inch (2.5 x 7.6 cm) boards to create a frame within your opening, and then 1 x 2 inch (2.5 x 5.0 cm) boards (recessed the thickness of your door) for the jamb. You may also choose to install trim around your opening on the ceiling.
I threw out the packaging with the installation template before I used it. How do I get a new one?
Contact Werner Customer Care at 1-877-553-7004 for a new template. Due to the importance of proper size/spacing, we are unable to offer it as a download at this time.
How do I adjust the length of the ladder for my 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 feet (2.13 m) to 9 feet 10 inches (3 m). 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.
How do I use the pole that is included?
It is an assist pole to help with opening and closing the ladder, and also with opening and closing the door.
My ladder won’t stay up in the attic. What’s wrong?
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.
I installed the ladder, but can’t get it to slide down to the floor.
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.
Different types of ladders are designed to keep you safe and productive when climbing or standing. Using the wrong style of ladder or simply ignoring the limitations of climbing equipment can result in a fall or serious injury.
Height reach Height is referring to the actual ladder height. Extension ladders should be 7 to 10 feet longer than the highest support or contact point, which may be the wall or roof line. The highest standing level is four rungs down from the top. The highest permitted standing level on a stepladder is two steps down from the top.

Reach height is the maximum reach assuming a 5’6” person with a vertical 12” reach.
Ladders are designed to safely hold up to a specific amount of weight. The Werner Performance System defines five different capacities using a color and star rating system. The Duty Rating is defined as the maximum safe load capacity of the ladder. A person’s fully clothed weight plus the weight of any tools and materials that are carried onto the ladder must be less than the load capacity.

Performance system
Werner offers ladder made from fiberglass and aluminum. Each material has characteristics which make it best for certain applications, or one material may simply fit the personal preferences of the user. For example, if working around electricity users should select fiberglass products due to their non-conductive side rails.
