We build our ownclamps & fittings.
Most specialty firms wait on a supplier when a job calls for a custom enclosure or fitting. ISS doesn't. Our in-house engineering and ISO 9001 machine shop design, machine, and deliver — so the fix isn't held up by a purchase order.
Explore the machine shopCustom enclosures and fittings engineered to the job, not pulled off a shelf.
Our certified shop — plus Phoenix Precision Machine — machines parts to spec.
We engineer, machine, and install, so response time stays measured in hours.
