We recommend Inox brand handles for their quality stainless steel construction, which hold up very well against our extra heavy doors. These can be purchased online from our own site here: isohardware.com/products/tl4-series-tubular-lock. Purchase a lockset for a 1-3/4" door with 2-3/4" backset. Because of the universal size of the 1-3/4" thickness, however, nearly any handle will work with our IsoDoor V.
IsoDoor V
IsoDoor V
Our IsoDoor V is our economical sound control door. Twice the performance in the mid to high frequencies compared to a solid wood door and nearly 4 times the performance in the lower frequencies. There are fewer options available with the IsoDoor V (no panel options, only common sizes available), but the price point fits with most projects and lead times are generally shorter. The IsoDoor V is a 1-3/4" thick door, weighing about 140 pounds in a 36" x 80" standard size. Generally used in more common assemblies, offices, vocal booths, paired with the IsoDoor SD or IsoDoor HD in a communicating assembly, etc. The standard IsoDoor V is a swinging door, like our IsoDoor SD and IsoDoor HD.
Our standard hardware prep for our IsoDoors is a 2-1/8" bore for a cylindrical lock with a 2-3/4" backset. Any additional prepwork required for your hardware will need to be done on site after installation is completed. We use redundant seals for the perimeter of the door along with a built-in automatic door bottom and acoustic threshold. Installation can be completed by any qualified contractor with extensive experience in installing doors. We do not have specific recommendations for installers, other than to only hire competent and experienced contractors to install our doors.

Frequent Questions
No, not really. We recommend king and jack studs on each side, which should be mostly standard. If using steel framing, add in wood support around the door opening. Otherwise, our continuous hinge distributes the weight of the door evenly from top to bottom, alleviating most of the pressure created by the extreme weight.
We ship our doors laying down in custom built crates. Doors with jambs 6" or narrower will generally remain pre-hung in their jambs. Doors with larger jambs, or 8' doors with any jamb size, will arrive with jambs knocked down and ready for assembly. The LTL carrier delivering will be a reputable company that will provide a lift gate if needed to lower the crate to the ground so no labor is required on the customer's end to offload.
We can build our doors in virtually any wood species. However, our IsoDoor V is a production door with the slabs made in semi-bulk in advance and only in birch. Large orders can be considered for custom wood species and sizes in our IsoDoor V. We generally recommend upgraded to the IsoDoor SD for such projects.
Each of our IsoDoors are available as double doors. Pricing for a double door version of our single door is right about twice the cost. The center gap is sealed using a steel astragal which is concealed with a wood cover, and a peel-and-stick seal on the inactive leaf is used to seal between the two doors. A flush bolt for the inactive leaf is also included for the inactive leaf.
