Sub-Zero 7020557 Right-Hand Freezer Basket Slide Assembly – OEM

7020557

67.58

The Sub-Zero 7020557 is a genuine OEM right-hand freezer basket slide assembly designed for 500 and early 600 Series built-in refrigeration units.
This slide assembly allows smooth extension and secure support of the freezer basket. Over time, slides may wear due to heavy load cycles, leading to:

Sticking or resistance during pull-out
Basket misalignment
Uneven extension
Excessive play or instability

Replacing worn slides restores factory glide performance and proper basket alignment.
Manufactured to Sub-Zero specifications, this assembly ensures:

Correct rail length and mounting geometry
Proper weight support
Smooth extension travel
Long-term durability

PARTS HELP

Frequently Asked Questions

Find clear answers about genuine OEM Sub-Zero, Wolf, and Cove replacement parts, compatibility verification, shipping, returns, and order support before you place an order.

Do you sell genuine OEM Sub-Zero, Wolf, and Cove replacement parts?

Yes. SubZeroParts.com focuses on genuine OEM replacement parts for Sub-Zero, Wolf, and Cove appliances. Our catalog includes parts for refrigerators, freezers, wine storage units, ice makers, ranges, ovens, cooktops, ventilation products, and other compatible appliance models.

How do I know if a part fits my appliance?

The best way to confirm fit is to check your appliance model number and serial number before ordering. Many Sub-Zero, Wolf, and Cove parts change by serial range, production version, or model variation. If you are not sure, use the Check Fit form and send us your model number, serial number, part number, and photos if available.

Why is the serial number important when ordering appliance parts?

A serial number can determine whether your appliance uses the current part number, an earlier version, or a different service replacement. Two appliances with the same model number may require different parts depending on the production range. Checking the serial number helps reduce incorrect orders, delays, and unnecessary returns.

Can you help me identify the correct part before I order?

Yes. If you are not 100% sure which part fits your appliance, send us your appliance details through the Check Fit form. Include the model number, serial number, part number if known, and clear photos of the part or rating plate. Our team will review the details and help you identify the correct compatible replacement part.

Do you ship Sub-Zero and Wolf parts across the United States?

Yes. We ship replacement parts to customers across the United States. Shipping options, delivery time, and availability may vary depending on the part, destination, carrier service, and current inventory status. Some large, fragile, or special-order items may require additional handling time.

What should I do if I already placed an order and need help?

If you already placed an order, use the Order Help form and include your order number, email address, and a short description of the issue. We can help with order status, tracking, shipping questions, returns, damaged items, wrong items, or compatibility questions related to your order.

Can I return a part if it does not fit?

Return eligibility depends on the item condition, product type, timing, and our return policy. Before ordering, we strongly recommend verifying compatibility by model and serial number. Electrical parts, installed parts, special-order items, or opened items may have restrictions. Please review the return policy before submitting a return request.

Are Sub-Zero and Wolf part numbers always the same as previous numbers?

Not always. Many OEM parts have current part numbers, previous numbers, replacement numbers, or service kit numbers. A previous number may be replaced by a newer part, but compatibility still depends on the appliance model and serial number. Product pages on SubZeroParts.com list current and previous numbers whenever available.
