AH2512 25 in W x 66 in L x 12 ft H Ceiling Aluminum Attic Ladder is rated 2.2 out of 5 by 5.
Rated 3 out of 5 by from Check Factory measurements The ladder was mounted in the box frame crooked. From one end to the other it was 1/2" off which would have made it open at a angle and possibly not open/close properly. They use jigs for hole placement so by not paying attention it was off. So I had to drill new holes , move the bolts and add extra washers to cover up the 2 holes per bolt.. Nowadays you have to check everything you buy. Even my 7 year old grandson could see the out of alignment. Step rungs could be another 1 - 2" wider as when you get to the steps with the plywood behind them you have to basically use your toes to step with

Rated 1 out of 5 by from quality control needs help Be careful when you buy this. The packing was fine but after I hired someone to put it up the wood was cracked and we were at the point I could not return. Can even find the info on the website to complain. The door itself is cracked and bent. The manufacturing of this product over tightened the screws. Now that's it's up I can see where it's not flush. If you get this door be careful

Rated 1 out of 5 by from Doesn't fit as advertised I have a new garage with a ceiling height of 9' 6" the installation went well until I pulled the ladder down. The ladder is 5" - 6" short, I had to build a platform to support the bottom of the ladder. After reading others with the same problem it's strange that Werner did not address this safety factor in past. Support to me to get the correct size! DUH................I have the correct size 8' to 10' ceiling is 9'6"

Rated 4 out of 5 by from Bent out of shape I picked up mine at Home Depot, he standard 25 by 54. Ididn't noticed the wooden door was warped till after I installed it causing a 1/4" gap. Yes, I used a level. I can see the warped door, not sure if it was cause by the way they are stored at the store. Maybe I should have picked one further back in the shelf as I remember the packaging looked newer.

Rated 2 out of 5 by from Warranty? What Warranty? (NOTE: I believe the model I have is no longer made. On the Home Depot receipt, the SKU shows "3632") I bought these stairs for a garage attic in 2005. They get used rarely, and I would be close to correct if I said they've been used about 50 times total over the last 12 years. Today, one of the articulating joints - the one with the red release handle - busted as I was folding the ladder to go back up. I called their customer support and was told there was nothing they could do for me because this was not a replaceable part. I have my original purchase receipt from Home Depot, but can't find the user guide to tell me what the warranty is, so...I got online and checked Werner's site. I was surprised to find an FAQ that said "we don't offer a warranty on our products, but we do stand behind them". I may be old school, but "stand behind them" has always meant to me "if it breaks, you can trust us to take care of you". What I got on the call today was lip service. Needless to say, I won't be buying another Warner ladder.

attic ladder door

my opening to attic is 20 3/4 " X 53 1/2 . can you make on for me ? ROBERT
Asked by: robert
Unfortunately we do not customer make any attic ladders. You might want to consider looking at the AA1510 which does not require a specific rough opening. The rough opening cannot be smaller than 18x24.

13 6" ceiling. How do i find ladder for this height?

Asked by: Dave
The Werner Co does not manufacture an attic ladder that will reach a floor to ceiling height larger than 12 feet. For a larger height, this would require an extension or straight ladder to reach this ceiling.

How To Use a AH2512 12' Ladder with a 12'5" Ceiling?

We very much would like to acquire one of the Werner aluminum attic ladders to use in a location where the floor to ceiling height is 12'5". Is there an extension that can be added to the AH2512 or some other way to make this work? Alternatively, can Werner make a custom ladder for this application?
Asked by: Ed
The AH2512 has a maximum floor to ceiling height of 12 feet. This ladder does not have extra sections or additions that can be added to reach the additional height. A height of 12 feet is the maximum that can be reached with a Werner Co. attic ladder.

My ceiling is 10' 7". I assume an aluminum attic ladder that goes to 10' 3" will not work for me?

Asked by: helper
For a 10'7" floor to ceiling height we would recommend our model AH2512 ladder. This will accommodate a floor to ceiling height of 10'5" to 12' and a rough opening size of 25" x 66".

My ceiling to floor is 10' 2". I already purchased the AH2512 . Can I make it work?

Asked by: Tom
The AH2512 has a minimum height requirement of 10 feet 5 inches. A lower floor to ceiling height requires the shorter ladder, the AH2510.

How to fit the finish architrave? Can the hinged portion be covered with the architrave and still allow smooth operation?

Is there an ideal thickness and width for the architrave?
Asked by: Jim'O
The modeling on the hinged end of the ladder should not cover the hinge. It should have between 1/4 inch and 3/8 inch reveal to allow the hinge to operate smoothly. There should be no interference on the hinge assembly. One way to verfy would be to open ladder, and then install the moldeling, being sure to avoid the hinge.

I have an 8'2" ceiling, but a 25"x66" rough opening. Can I cut the bottom of the AH2512 shorter by 2' to work for me?

Asked by: Mike
The AH2512 has a minimum floor to ceiling height of 10'5". This ladder cannot be installed into a shorter height because the middle hinge will interfere with the feet. To safely reach the 8'2" floor to ceiling height, the AH2510 should be used. The AH2510 has a 54 inch long rough opening, so the rough opening will need framed inwards to properly secure the ladder.

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 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.

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.
