Q - How thick is the steel?
A - The steel on the 2810HR and 210NR is 14 Gauge, which is thicker than you might expect. The steel plate is thicker than a US quarter, or about 1.62mm. Also, if it helps, the last photo of the 2810HR and 210NR Joist Reinforcers provides a image that shows the edge of a Reinforcer next to a screw, pen, and the 1/8" drill bit that comes in the kit. It's a very heavy duty steel and weighs about 5lbs. Hope this helps.
Q - What are Joist Reinforcers?
A - Skyline Joist Reinforcers are light gauge steel plate add-on devices specially designed to strengthen Floor Joists that have been compromised by hole and notch cuts for utilities such as electrical, and plumbing, as well as HVAC. All of our Joist Reinforcer products have been designed by engineers. Some have Intertek Code Compliance Reports, others come with engineers stamp.
Q - I don't see a that you have a product for my application. Can you design a reinforcer for my situation?
A - It's very likely that we can. We've provided many specially engineered Reinforcers over the years, and we have more experience in solving the challenge of holes and notch cuts in floor joists than anyone we know of. Give us a call to discuss your application. Call 540-589-9669.
Q - What comes with your Joist Reinforcers?
A - The Reinforcer itself, which usually consists of one or two plates. All the fasteners, instructions, the code approval documentation, a drill bit for pilot holes, and a square tip driver. Pretty much everything you need to do the installation.
Q - Can I put more than one Joist Reinforcer on a Joist?
A - No. But you can put Joist Reinforcers on multiple Joists. This gives you the possibility of running electrical and plumbing right through a series of Joists, as needed.
Q - How strong are Joist Reinforcers?
A - We have completed a great deal of testing over the years. The easiest way to explain the strength our products are is that tests have shown that once you add a Joist Reinforcer to a Joist that has been cut, it will be stronger than the Joist was before it was cut. This means there is no compromise in the strength of a Joist once the Reinforcer has been installed, provided the size of the holes does not exceed the allowed size on the documentation. This is 6" diameter for a 2x10, or 2x12, and 4" diameter for a 2x8.
Q - Can you help me fix this? The plumber cut two large holes in two joists. The inspector is telling me I need to replace the joists. The holes in the 2 x 10's are nearly 6" around and the plumbing is already run. Do you have a product that will solve the problem so I don't have to replace the joist and have the plumber come back and reroute the pipe?
A - It sounds like a standard 2810HR will solve this. It is designed for 2x8, 2x10, and 2x12's, and can handle a hole up to 6" in diameter. The pipe is run, but there are two plates so you can get the top plate up and around the top of the pipe, and slide the bottom plate under the pipe. If this works for you we can send them out the same day, and you could have them as early as tomorrow if you don't mind paying for expedited shipping. If regular UPS ground is fast enough you would probably still have them within three days.
Q - Are you saying I can run plumbing pipes through joists instead of under?
A - Exactly!
