Cranks, handles, locks, rollers, weatherstripping, and more. We stock thousands of parts—and if we don't have it, we'll find it.
That broken window crank. The patio door handle that snapped. The weatherstripping that's crumbled away. Sometimes you don't need a whole new window—you just need the right part.
We stock one of the largest selections of window and door hardware in the region. Parts that big box stores have never heard of, we probably have on the shelf. And our staff actually knows which part you need—bring in the broken one and we'll match it.
This is what we do. We've been doing it for 55 years.

Casement window operators wear out. We stock hundreds of styles—old and new. Bring in the broken one and we'll match it.
Sash locks, cam locks, sweep locks. Single and double-hung, sliding, and casement varieties.
Hold your windows up. Block, spiral, and channel balances for single and double-hung windows.
Let double-hung windows tilt in for cleaning. Small parts that make a big difference.
Pile, fin, bulb, foam, and compression types. Stop drafts and save on heating. We cut to length.
Awning and casement window hinges. Standard and egress styles. We match discontinued hardware.
Interior and exterior handles for sliding patio doors. Various styles and finishes.
Security locks, foot locks, and multi-point locking systems.
When your sliding door gets hard to move, rollers are usually the culprit. Dozens of styles in stock.
Handles, pulls, closers, rollers, and latches for screen doors.
Door bottom sweeps and weatherstripping. Stop drafts and keep out pests.
Replacement door thresholds in aluminum, wood, and composite.
Easiest way. Bring the broken part to our counter. We'll identify it and find a match.
Can't remove it? Email clear photos showing the part and how it mounts. Include measurements.
For complex situations, we send a technician to assess and can often repair in one visit.
Our counter staff has decades of combined experience. When you bring in a weird part, they usually recognize it.
Thousands of parts—far more than any big box store. Many "discontinued" parts are on our shelves.
If we don't have it, we'll find it. We have supplier relationships across North America.
Hardware parts are our bread and butter—we price them fairly because we want you to come back.
"I had a broken window crank assembly that is more than 30 years old. I brought it in to Centennial and within minutes had a new replacement that works perfectly."
"I visited to get replacement wheels for a screen door, and I was amazed how quickly they were able to help. Within 2 mins I had my new wheels picked out and installed."
"A quick thank you for knowledge and parts! I went looking for patio door roller wheels and was provided exactly what I needed by friendly helpful staff."
Do you install the parts you sell?
Yes, if needed. You can buy parts for DIY installation, or we can send a technician to do the work.
What if you can't identify my part?
Rare, but it happens. We'll do research, contact suppliers, and do our best. Sometimes it takes time; sometimes the part doesn't exist anymore.
Can I return parts?
Unused parts in original condition can be returned. Special orders are generally non-returnable.
