How do I measure garage door track radius?
Track radius refers to the curved portion of your garage door track as it transitions from vertical to horizontal. To measure, look at the curved section and measure from the inside corner of the curve to the top of the track. Most common residential sizes are 12” radius (tighter curve, more headroom needed) and 15” radius (gentler curve, smoother operation).
What’s the difference between 12” and 15” radius tracks?
The difference is the curve angle. 12” radius track makes the door turn upward faster and requires less backroom. 15” radius track provides a smoother transition, reducing stress on rollers and hinges, but needs more ceiling clearance.

What type of garage door rollers should I choose?
Garage door rollers come in several styles:
- Steel rollers (no bearings): Strong but noisy, best for low-cycle doors.
- Steel rollers (with ball bearings): Durable, smoother than basic steel, but can be loud.
- Nylon rollers (with ball bearings): Quietest and smoothest option, long-lasting, ideal for residential doors.
Why should I replace more than just one roller at a time?
While you can replace just one roller, rollers wear down at roughly the same rate. Replacing all rollers ensures smoother travel, reduces strain on the opener, and prevents future breakdowns. Mixed roller types (steel vs nylon, bearing vs no bearing) can also create uneven wear.
How do I order the correct replacement garage door roller?
Follow this 3-step process:
- Determine size: Measure the roller wheel diameter and the stem length.
- Select type: Choose steel or nylon, and whether you want bushing or ball bearing.
- Order now: Shop our rollers and receive your replacement in just a few days.
🔹 Tip: Inspect your current rollers to see if they have ball bearings inside, and match the wheel material.
Why does my door rub or scrape against the track?
This can be caused by misaligned tracks, worn rollers, or bent hinges. Check track alignment with a level and make sure all bolts are tightened. Replace rollers if worn or damaged.
Why does my door make loud popping or grinding noises?
Common causes include:
- Dry or worn rollers → apply lubricant or replace.
- Hinges with cracked sleeves → replace hinge.
- Tracks rubbing due to misalignment → adjust and tighten.
When should I replace my hinges or rollers?
Hinges should be replaced if cracked, bent, or making loud popping sounds during door travel. Rollers should be replaced if the wheels wobble, bearings fall out, or if they’re over 7 years old in high-use doors.
Can I install the WD-339621 Operator Bracket on a door section without a bottom rib?
Yes. The larger metal piece at the top of your panel is a U-bar, and the small lip at the bottom of the panel is the rib referenced in installation instructions. Your door has an extra-heavy duty U-bar at the top, and the standard rib at the bottom. The operator bracket attaches to both points. You can safely screw into the U-bar on the top of the panel and the rib at the bottom as shown in the diagrams.
