The right replacement depends on what has failed: a center-pivot window may use a sash pivot bar that engages a pivot-lock shoe, while the other products below are concealed 360-degree pivot hinges intended mainly for doors or cabinets. The WRS bar is the most directly relevant option for a compatible Harvey window. The remaining choices may suit projects that specifically call for a concealed pivot hinge, but their listed dimensions and intended use should be checked against the existing hardware before purchase.
| Product | Best For | Key Check |
|---|---|---|
| WRS L-shaped pivot bar | Compatible Harvey tilt-window sash repairs | Match the L-shaped head and original size |
| Antrader 360-degree hinges | Basic door or window pivot-hinge projects | Confirm the 4-inch dimensions and mounting pattern |
| uxcell 10-piece concealed hinges | Small cabinet or swinging-door applications | Check the 57 x 16.3 mm size and hole diameter |
| Stainless concealed hinge set | Projects needing 100 mm pivot hinges | Verify the 25 mm hole spacing |
| 4-inch stainless pivot hinges | Window, door, or cabinet fittings | Check the 100 x 30 mm size and screw layout |
WRS L-Shaped Window Pivot Bar

Best for: DIY homeowners or repair professionals replacing a worn or damaged pivot bar in a compatible Harvey tilt window. This is the only listed product specifically described as a window sash pivot-bar replacement, making it the closest match for a center-pivot window repair.
The die-cast zinc bar mounts at the lower corner of the sash and rides in the jamb’s pivot-lock shoe. Its L-shaped head must match the shoe slot. Replacing the bar may address a sash that does not stay in place or move smoothly, without replacing the entire window.
Limitation: The listing says this part is sized to the original and is not a universal fit. It is not stainless steel. Check the existing part’s profile and dimensions before ordering.
Antrader 360-Degree Pivot Hinges

Best for: Buyers needing a four-piece set of general pivot hinges for a door or a suitable window-fitting project. The package includes mounting screws, and each hinge is listed at 100 x 32 x 5 mm.
Choose this set if its dimensions and mounting arrangement match the hardware being replaced. The product is described as a metal door pivot hinge, so it is not a direct substitute for the Harvey-style sash pivot bar above. Its inclusion here is for buyers whose project calls for a separate 360-degree pivot hinge rather than a sash bar.
Limitation: The listing does not specify a window-brand fit or provide a load rating. Confirm the application and mounting pattern before use.
uxcell 10-Piece Concealed Pivot Hinges

Best for: Projects needing multiple small, concealed hinges for swinging cabinet doors or similar fittings. The package contains 10 stainless steel hinges, each measuring 57 x 16.3 mm, with 5 mm hole diameters and 1.7 mm thickness.
The listing describes 360-degree rotation, quiet operation, and a concealed design. Stainless steel is specified as waterproof and corrosion-resistant. Choose this set when the compact dimensions suit the project and a nearly hidden hinge is wanted.
Limitation: The stated application emphasizes cabinets, not a specific center-pivot window system. Do not assume it will fit a window sash or carry a particular load; the listing provides no load rating.
Stainless Steel 360-Degree Concealed Hinges

Best for: Buyers seeking four larger concealed pivot hinges for a door, cabinet, or other fitting that uses a 100 mm hinge. Listed measurements are 100 x 16 mm, with 25 mm hole spacing and 3 mm thickness. The product description identifies the material as 304 stainless steel.
The listing describes smooth 360-degree movement and a concealed appearance. Consider this option when those measurements match the current fitting and the project needs a corrosion-resistant stainless steel hinge.
Limitation: The product description refers to doors and cabinets and does not identify a specific center-pivot window model. Check the hole spacing and confirm the hardware type before treating it as window replacement hardware.
Four-Inch Stainless Steel Pivot Hinges

Best for: Buyers whose project calls for four 360-degree pivot hinges measuring 100 x 30 mm. The package includes screws, and the listing names windows, doors, cabinets, cupboards, shutters, and tool boxes as possible applications.
The hinges are described as stainless steel, moisture-proof, corrosion-resistant, and wear-resistant, with a surface-drawing treatment. Choose this option if the broad stated application and dimensions match the existing fitting.
Limitation: A general window-use description does not establish compatibility with a specific center-pivot sash. The listing does not provide a window model fit or a load capacity, so verify both the hinge layout and intended use.
Buying Guide: How To Choose Center Pivot Window Hardware
Is the failed part a sash pivot bar or a hinge?
Inspect the hardware at the sash’s lower corner and compare it with the product descriptions. A pivot bar engages a pivot-lock shoe in the window jamb; a concealed pivot hinge is a different fitting used to let a door or panel rotate. If the existing part is a sash bar, a general door hinge may not replace it.
Which measurements should you check?
- For a sash pivot bar, compare its overall size and head profile with the original part and the pivot-lock shoe slot.
- For a concealed hinge, compare length, width, thickness, hole diameter, and hole spacing.
- Check the number of hinges required and whether screws are included when that matters to the installation.
Does the material determine compatibility?
No. Material can help distinguish product construction, but it does not establish a fit. The WRS bar is die-cast zinc; the other listed hinges are described as metal or stainless steel. Match the fitting type and dimensions first, then consider material features relevant to the project.
When should you avoid a universal-fit assumption?
Avoid assuming that a hinge marketed for windows fits every center-pivot window. The WRS bar is explicitly not universal, and the other hinge listings do not identify specific window models. If the existing hardware cannot be matched by shape and measurement, identify the window system or consult a window-parts supplier before ordering.
Frequently Asked Questions
Are center-pivot window hinges and pivot bars the same part?
No. A sash pivot bar engages with a pivot-lock shoe, while a pivot hinge is a separate rotating fitting. Identify the failed component before choosing a replacement.
Which product is most directly intended for a window sash?
The WRS L-shaped pivot bar is described as a replacement for compatible Harvey tilt-window sashes. Its head profile and size must match the existing hardware.
Can a 360-degree concealed hinge replace a window pivot bar?
Not based on the product information provided. These hinges have different listed forms and applications; confirm the replacement part matches the original component.
What should I measure before ordering?
Measure the original part’s overall dimensions, shape, thickness, and hole layout as applicable. For a pivot bar, also compare the head with the pivot-lock shoe slot.
Are all the listed products stainless steel?
No. The WRS pivot bar is die-cast zinc, and the Antrader product is listed as metal. The remaining hinge listings specify stainless steel.
