Can the trestle part of the ladder be removed to make a 16' stepladder?

Asked by: BJS
The extension trestle section cannot be removed from the ladder. The ladder can be used without extending the trestle section to be used as just a twin sided step ladder.

How high can a person stand and work on this ladder?

Do they need to stop 2 steps down from the knuckle of the A frame or 2 steps down from the top of the extension. In what conditions can 2 people work on the ladder and at what height?
Asked by: Jed Baked
The extension trestle ladder has a variety of acceptable uses. When using the ladder as a step ladder or a twin step ladder, the user cannot climb above the highest labeled step stating where the user can climb. This is the same rule with a step ladder. One user can climb on each side of the ladder, but only the A frame portion, not the extension. A single user may climb the center extension portion of the ladder, following the labels for the maximum allowable height.

if i am tied off to the stucture with a full body harness can i then straddle the extension part of the ladder and use two hands to work

Asked by: pipe fitter
No you cannot straddle the ladder at any point in time. When using the ladder in the extension position you need to be no more than 4 rungs from the top. When using in the stepladder position you cannot be anymore than 2 rungs from the top.

Is the tressel extension made to climb on or support a scafold?

I need to use a six foot ladder to remove a ceiling tile. After the tile is removed then I need to use a ten foot ladder to allow me to climb up into the ceiling area above the tile height. Is the tressel made to extend above the tile height so peole can climb up it to get into the area above a ceiling tile?
Asked by: Nick
You can climb on the extension part of the trestle ladder. You want to follow the same rules as the extension ladder and stand 4 rungs down from the top. It will also hold stages up to 14" in width.

Are there wheel attachments that work with this ladder?

Asked by: K

Why can't you straddle the extension?

Three points of contact are required by OSHA. And you have both feet, both thighs squeezing the top one or two rungs(depends on your height which run your feet are on, second or third) and your rear on that top rung, that's 5 or 7 points of contact. It is the same as if your sitting on an I beam with your feet on the bottom flange.
Asked by: Brad
When you are using the E7416 in the extension position, per OSHA this must follow the same rules as a standard extension ladder. This rule states that you cannot go any higher than 4 rungs from the top of the ladder.

Can you secure yourself to the rails while using the extension part of the ladder with your leg?

We use these ladders extensively in our fire sprinkler installations and use the straight ladder portion to reach those tight areas. The normal practice for us is to run one leg through the rungs and lock-in on the side rail. Is this a good safety practice or should we consider using a belt hardness to secure ourselves to a stationary object capable of carrying the weight stress of the installer.
Asked by: Larry Perez
The ladder is not to be used in this matter as you described, it is not safe. Please contact Customer Care at 888-523-3370 Monday through Friday from 8:00 AM to 5:00 PM.

How much weight can the ladder bare on the side of the ladder without it tilting and falling over on its side?

If a person who is wearing a harness secures himself to the top two-three rungs, and then falls to the side of the ladder, will the ladder be stable enough to remain upright? I understand the ladder has a 300 pound duty rating, but in this fall situation, the weight would be on one side of the ladder (not near the rungs).
Asked by: Sarah
You are not to tie off or secure yourself to any ladder! Ladders are not designed to be used in this manner.

Ceiling Height

Our false ceiling is at 20' and the ladder needs to extend 4 feet beyond that. Will the E7416 work? If not, do you have something that will work?
Asked by: Greg
The E7416 is a 16' twin step ladder, with the extension trestle that extends through the top of the ladder. With the trestle at full extension, the ladder height is 26'.

Is there a platform attachment that can be attached to the upright portion of the ladder that a worker can stand on for comfort when working ?

Asked by: AlohaBrian
The Extension Trestle ladders do not have an accessory platform available. Using two trestle ladders, a stage and guardrails, the trestle ladders can be assembled as the base units for a trestle ladder scaffolding.

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.
