The whole idea

We'll take care of it.

It’s the sign on our wall and it’s the reason customers stay. In an ever-changing economic landscape, where it’s difficult to reach someone on the phone, we might be called a bit old school. We pick up the phone. No answering service… only a live voice. Here’s what that means for you:

We answer

Real people, same day. Call us in an emergency and we make it happen.

We stock for you

We keep partials and hardware on hand — so a supply crunch doesn't stop your line.

Fair price, first time

You get our best price up front — no gouging, no games. That's been the rule since day one.

What we make

Quality Parts, Big Impact.

From a few thousand pieces to a few million a year — in nylon, styrene, ABS, acetal, polycarbonate, polypropylene, and PVC… just to name a few.

Window & Screen Keys

Radius and corner keys by the millions.

Weep Plugs

PVC plugs that keep the rain out of every extrusion — we make millions.

Egress & Latch Handles

Full assemblies — handle, catch, keeper — built and kitted in-house.

Housing & Mounts

Instrument hangers, detector housings, TV hangers — delivering structural integrity where it matters most.

Spacers & Small Parts

The unglamorous pieces, in the right material, at the right tolerance.

Built Assemblies & Kits

Rivets, springs, foam, wool pile — assembled, bagged, and ready to install.

Industries we serve

Why it matters

When the supply chain broke, we didn't.

When component shortages hit in 2020 and 2021, many builders found themselves stranded while their molders scrambled for hardware. We didn’t just keep up; we gained business and kept every promise we made—thanks to proactive material planning and rock-solid supplier partnerships.
