I am investigating an existing wood truss. The pressed plates used are stamped with “Combo Lock.” Do you happen to have any information on them? From what I have been able to determine, they have not been readily used in the last 10 to 15 years.
Consider this statement from a set of construction contract documents: “The Truss Manufacturer is responsible for inspecting the truss installation, bracing, anchorage and bearings and preparing a letter of verification stating that trusses are installed and braced properly.” At first glance, it may seem that the truss manufacturer is the most logical party to perform such an inspection. They are the truss experts, are they not?
Are trusses required to have tags on all bearings that are not at the heel location? What about tags on webs requiring lateral reinforcement?
What do you mean by the term “trusses”? Are there different kinds of trusses? What are their uses?

I'm trying to find out who the truss manufacturer was that built the trusses in my home. I was told that there is usually a stamp on the side of the bottom chord. All I found was “2400F 2.0E.” What am I looking for? The other chords only have material stamps. Can you tell me what kind of information I should be looking for to find out who the manufacturer was?
During a home inspection, the inspector stated that the spacers were not secured at the attic trusses. What did the home inspector mean by this?
How do I go about estimating the weight of a roof truss framing system? Is there a table of span vs. pitch vs. weight of trusses? Is there a guide available that shows how the components of various roof styles (hip, gable, etc.) are commonly framed and the associated terminology?
I am conducting an investigation on the costs associated with building a 15,000 sq. ft. addition to an existing school building. I need to determine if wood trusses, steel bar joists or light gauge steel trusses would be the most economical material for the building system. The truss spans range from 42 ft. to 56 ft.
How much weight can a wood truss hold, when it’s made with 2x4 material and spans 36 ft. with a 4/12 pitch. I would like to hang things from the ceiling and am wondering if it is safe. I live in an area where there are heavy snowstorms. Also, how much exposure to the weather can a truss handle before there is a problem?
We are looking into developing the attic space above our garage into a media room. The garage is attached to the home and we would enter this area from the living room. We recently read if you have a truss system that in order to develop the attic, one would have to replace the entire roof with conventional construction. My question is: can we safely develop this trussed area above our garage?
Does SBCA produce any products detailing how to market and sell roof and floor trusses to builders for whom stick framing has been the standard way of building? Products that detail the cost savings when compared to traditional stick framing?
Is it possible to attach deck ledger boards to the ends of floor trusses? If not, are there any modifications that would make this possible?
Do you have any information on the use of in-floor radiant heat with 4x2 open-web floor trusses? Are there any adverse effects to the lumber as a result of moisture build up?
While building a new 2-story home, I found the need to use floor trusses between the 1st and 2nd floors. Is it true that I must also use roof trusses?
How long has the truss industry been around and where did it start?
I own and live in the middle unit of a one-story tri-plex that has a truss-framed roof. The interior has high ceilings that would potentially allow the addition of a second floor room. I am contemplating adding a shed dormer to create a second story bedroom. Do you have any suggestions as to how a shed dormer could be added? I am familiar with how to frame up a shed dormer if the original framing were rafters and a ridge board, but the truss construction has thrown me for a loop.
I am building a home and want to use floor trusses. How can I find a local manufacturer?
I need to put a new roof on my single-family dwelling. The house originally had gable and soffit/eave vents. The roofing contractor suggested that we install a ridge vent when new roof is installed. Should the existing gable vents be blocked off or does it not matter? I have read some debates about whether or not the combination of gable and ridge vents substantially reduces the effect of the soffit vents by having the intake now at the gable vents and exhaust at the ridge. Would this type of ventilation affect the truss warranty?
I am doing research for clients who have flat roof trusses to which they are adding a second story. We are now looking for information on the trusses to determine what their load capability is. What do you need to know to help us determine this?
We are changing plans from a two story home to a one story home. The original roof pitch is 12/12 with three dormer windows, one large one in the center and a smaller one on either side. Can you tell us what pitch would be advisable under this new plan still using the dormers?
We have been using Turb-O-Webs for about four months. We are very happy with their performance, although there have been a few ripples along the way. The main thing that concerns me at present is the need for performance documentation and testing data. Do you have anything that will help, or know of people or organizations that could offer assistance?
We would like to know if there is a problem with using wood floor trusses with masonry bearing walls without a ledger. Our local supplier has told me that encasing the wood truss in the masonry wall could be detrimental to the truss due to moisture. What, if any, suggestions do you have for this condition? If a bottom chord bearing is used, do the trusses need fire cuts? The two-story building contains masonry bearing walls with wood trusses on the second floor and wood trusses at the roof.
