How to Find the Right Replacement File Bar Size and Fit for your file cabinet
How to Find the Right Replacement File Bar
Missing, bent or lost file bars are the most common reason a good file cabinet stops working. This is the same process our parts specialists use every day to match bars to cabinets from Steelcase, HON, Allsteel, Haworth, Herman Miller, Knoll, Office Specialty and many more, including brands that are no longer in business.
Step-by-Step: Identify Your Cabinet
-
Look for a brand label
Check the front and back of the cabinet, and the inside side walls of each drawer. Manufacturers often put a sticker or stamp inside the drawer where it's easy to miss.
-
No label? Check the lock
If the cabinet has a lock, look for the number stamped on the lock core next to the keyhole. That number often points straight to the manufacturer. For example, a customer's lock number recently told us her lateral file was an Allsteel. Some lock numbers are shared by many brands, so we may still ask for the measurements below.
-
Measure the cabinet's outside width
Measure the drawer front from side to side. Lateral files are commonly 30", 36" or 42" wide. This is the size most of our file bars are listed by.
-
Measure an existing bar (if you have one)
Measure the bar from tip to tip, and measure the height of the hook or insert stem, which is the part that drops into the slot in the drawer. Two bars for the same cabinet width can differ by a fraction of an inch.
-
Take a photo
A close-up of the end of the bar and the slot it sits in is the single most helpful thing you can send us. It lets us confirm the match before you order.
-
Order or ask us
If the brand and width match a listing, you can order directly. If you're unsure, send us your measurements and photos and a specialist will reply with the exact part.
Measurement Checklist
| What to measure | Where | Why it matters |
|---|---|---|
| Cabinet width | Outside of the drawer front, side to side | Determines the bar size family (30", 36", 42", etc.) |
| Bar length | Existing bar, end to end | Bars for the same width can vary slightly by brand and era |
| Hook / stem height | The part of the bar that drops into the drawer slot | Must match the slot so the bar sits securely |
| Lock number | Stamped on the lock core next to the keyhole | Often identifies the manufacturer |
| Approximate age | Purchase date or label date | Some brands changed bar styles over the years |
Wooden Desk or Credenza? Add Hanging Files Without Routing
Many wood desks were never built for hanging files, or the original clips were lost in a move. Our hanging file bracket clips hold a standard 1/8" thick steel file bar and slip over the edge of the drawer box. No routing, no extra drawer wall. Choose from hook, flush, top-mount and rail-connector styles, and we'll cut the file bar stock to your length (6" to 39"). Works for letter or legal files.
Files Sticking? Quick Troubleshooting
- Check the drawer lip. On older cabinets the top lip can bulge inward. Gently tapping it back into place from the inside often solves sticking files.
- Check the rail direction. Side-to-side rails run across the drawer; front-to-back rails run from the front to the back. Make sure you have the layout you want.
- Check your file stoppers. A missing or misplaced stopper lets files slide too far and jam.
- Load safely. Keep the heaviest files in the bottom drawer for better weight distribution and stability.
"I was getting nowhere talking to other vendors trying to find the rails I needed. Your firm has what I need, takes only one contact to figure out the correct product number, and it arrives a few days later!"
