For double-hung tilt windows, choose replacement hardware by matching the part type, dimensions, and window series. The Andersen-compatible sash lock is best for a specified Andersen window; the two plastic latch sets are options for replacing tilt latches when their size and design match. A spiral balance pivot bar addresses sash movement, while the cat perch is an accessory—not a repair part.

Andersen-Compatible Metal Sash Lock
This metal lock and keeper is listed for Andersen 200 Series Perma-Shield Narroline double-hung windows made from 1968 to present, and Andersen 400 Series Tilt-Wash double-hung windows made from 1994 to present. Its materials are corrosion-resistant zinc alloy and reinforced steel springs.
Best for: Owners who have confirmed their window’s series and type and need a sash lock replacement. It is the only listed lock-and-keeper product here, making it the clearest match for that repair.
Check before ordering: The listing distinguishes between Narroline and Tilt-Wash models. It specifically says the 200 Series Narroline fit is not for Tilt-Wash windows. Confirm the window identification and existing hardware before purchase.
Honoson Four-Piece Plastic Tilt Latches
Honoson’s set contains four spring-loaded plastic latches: two left-hand and two right-hand pieces. Each latch measures 3 by 1 inches. The product description says the plastic is designed to resist breaking or deforming during use.
Best for: Buyers replacing a matched pair of tilt latches who need both left- and right-hand parts or want spare pieces. Its stated dimensions provide a useful initial comparison with the existing latch.
Check before ordering: Screws are not included. Measure the old latch and compare its shape and mounting details; the listing does not establish fit for every window brand or model.
White Spring-Loaded Tilt Latch Set
This four-piece set includes two left-hand and two right-hand plastic latches. Each measures 76 by 26 millimeters, approximately 3 by 1 inches, and has a built-in spring for locking and unlocking.
Best for: Buyers looking for a white latch set with clearly stated dimensions and left/right pieces. Compare its measurements with the original hardware before choosing it over the Honoson set.
Check before ordering: The listed size alone does not confirm compatibility with a particular window. The product information does not specify a brand or model fit, so verify the latch profile and mounting arrangement as well as the dimensions.
3758 Spiral Balance Pivot Bars
This four-pack of 5/8-inch-high 3758 spiral balance pivot bars is described for Prime-Line tilt windows and single- or double-hung vertical sash windows. The bars are made of stamped steel and are intended to connect with a spiral balance system to support sash movement.
Best for: Buyers replacing a worn or damaged pivot bar when the existing part and window hardware match the listed 3758 type. A compatible pivot bar can help restore the sash’s movement and support.
Check before ordering: This is a pivot-bar replacement, not a complete spiral balance. Confirm the original part’s size and style; the listing does not claim universal fit.
Adjustable Cat Perch For Hung Windows
This adjustable perch is an accessory for double- and single-hung windows, including windows with a lip. Two telescoping rods adjust its length from 18.1 to 30.7 inches. The listed construction includes natural rubber wood, a reinforced metal frame, and 900D Oxford cloth; the stated weight capacity is 50 pounds.
Best for: Cat owners who want a window-side resting place and have a compatible hung window within the perch’s adjustment range. It is included as a window accessory, not as double-hung window repair hardware.
Check before ordering: The listing says it is not compatible with crank, casement, awning, or slider windows. Confirm the window type and available width before selecting it.
Buying Guide: How To Choose Double-Hung Tilt Window Parts
Which part needs replacement?
Identify the failed component before shopping. A sash lock secures the window; tilt latches release the sash so it can tilt inward; and a pivot bar connects the sash to the balance system. These parts do different jobs and are not interchangeable. A perch is an accessory, not a window component.
How can you check compatibility?
Record the window brand, series, and model if available. Compare the replacement part with the original hardware, including its dimensions, left- or right-hand orientation, shape, and mounting points. For brand-specific parts, confirm the exact window type: the Andersen lock listing separates 200 Series Narroline from 400 Series Tilt-Wash fit.
Should you choose plastic or metal hardware?
Material is only one selection factor. The two latch sets are plastic and have stated dimensions; the Andersen lock uses zinc alloy and reinforced steel springs, while the pivot bars are stamped steel. First establish that the replacement matches the existing component. A different material does not by itself guarantee fit or improved performance.
What should you verify before installation?
Check how many parts are included, whether left- and right-hand versions are supplied, and whether screws or other installation items are included. The Honoson listing explicitly says screws are not included. If a sash is difficult to operate or will not stay supported, identify whether the issue involves the latch, pivot bar, or balance system before replacing parts.
Frequently Asked Questions
Do all tilt latches fit double-hung windows?
No. Compare latch dimensions, shape, hand orientation, and mounting details with the existing hardware. The listed latch products do not claim universal window compatibility.
Can I use the Andersen sash lock on any Andersen window?
No universal fit is stated. The product lists particular 200 Series Narroline and 400 Series Tilt-Wash windows, with a specific exclusion for 200 Series Narroline Tilt-Wash windows.
Are tilt latches and sash locks the same part?
No. A tilt latch releases the sash for tilting, while a sash lock secures the window. Choose the replacement based on the function of the original part.
Does the pivot bar replace the entire window balance?
No. The listing describes a pivot bar used with a spiral balance system, not a complete balance assembly.
Can the cat perch fit a slider window?
The listing says it is not compatible with slider windows. It is described for double- and single-hung windows, subject to its adjustment range.
