If you’re contacting us about an existing order, please include your order number.

We focus on:

• Vehicle lifts and lift accessories
• Garage equipment and related materials
• Selected products that support safe, efficient garage or shop operations

We don’t aim to sell “everything”—just the equipment that belongs in a serious garage environment.

Choosing the right lift depends on:

• The types of vehicles you’ll be lifting (size and weight)
• Your ceiling height and floor space
• Whether this is a home garage or commercial shop
• Your preferred style (2-post, 4-post, storage vs service, etc.)

You can contact us with details about your space and vehicles, and we’ll help you evaluate options. Final compatibility and installation decisions should always be confirmed with a qualified installer or engineer.

Any properly designed lift must still be properly installed, used, and maintained to be safe. We select products with safety in mind, but:

• Lifts must be installed by qualified professionals
• Rated capacities and manufacturer instructions must be followed
• Regular inspection and maintenance are essential

No lift is safe if installation and usage guidelines are ignored.

Dunfer does not directly perform installation.

• You are responsible for hiring a qualified, licensed installer or contractor.
• Many manufacturers and local dealers can recommend experienced installers.
• Always confirm your installer understands lift requirements, local codes, and safety standards.

We can offer general guidance on what to ask your installer, but we are not your engineer or contractor.

Vehicle lifts carry heavy loads above and around people. Improper installation can cause:

• Structural failure or collapse
• Vehicle drops or tipping
• Serious injury, death, or major property damage

Professional installers help ensure:

• Concrete, anchors, and structure meet the required specifications
• Electrical and hydraulic work is code-compliant
• The lift is assembled and tested according to manufacturer instructions

We strongly recommend professional installation. Even experienced DIYers can miss critical details like concrete quality, anchor placement, or electrical requirements.
Installing a lift incorrectly can:

• Void manufacturer warranty
• Create severe safety hazards
• Lead to code violations and insurance issues

At a minimum, you should review:

• Concrete thickness and strength where the lift will be anchored
• Ceiling height, beam locations, and overhead obstructions
• Electrical requirements (voltage, breaker size, dedicated circuits)
• Vehicle lift points and loading patterns for your typical vehicles
• Local building, electrical, and safety codes that apply

In most cases, you can check out as a guest, but creating an account can help you:

• Track orders and view order history
• Save basic information for faster checkout
• Access documents and details for future reference

If you need to make changes or cancel:

• Contact us as soon as possible at contact@dunfer.com or by phone.
• If your order has not yet entered processing or shipped, we’ll do our best to accommodate changes.
• Once heavy or freight items are processed or shipped, changes may be limited and the order may need to be handled under our Returns & Refunds policy.

You can:

• Check your order confirmation email for basic details.
• If tracking is available, we’ll send you a shipping or tracking email once the order ships.
• Contact us with your order number if you need additional information.

We primarily accept:

• PayPal
• Major debit/credit cards processed securely through PayPal (subject to PayPal’s terms and eligibility)

Available options may vary over time and by location.

Typically:

• Your payment method may be authorized when you place the order.
• The final charge usually occurs when your order is accepted, processed, or prepared for shipment (depending on the payment provider’s rules).

If your payment is declined or flagged as suspicious, we may need to place your order on hold or cancel it.

We use third-party payment processors such as PayPal to handle payments securely.

• Full card details are processed and stored by the payment provider, not directly by Dunfer.
• We may retain limited billing details (like transaction ID or payment method type) for records.
• You should also protect your own account passwords, devices, and email access.

We primarily ship to addresses within the United States.
Some heavy or oversized items may have additional limitations, especially for:

• Remote areas
• P.O. Boxes or APO/FPO addresses
• Locations that are difficult for freight trucks to access

Any restrictions will be noted on product pages or at checkout where possible.

Most lifts and heavy equipment ship via freight (LTL) carriers, not standard parcel.
This usually means:

• Curbside or driveway delivery (not inside your garage or building)
• A large truck with specific access needs
• Possible need for liftgate service if you don’t have a dock or forklift

Additional services like liftgate or appointment delivery may involve extra fees.

Shipping costs are calculated at checkout and are based on:

• Weight and dimensions of the products
• Destination address
• Type of delivery (parcel vs freight)
• Any special services needed (liftgate, scheduled delivery, etc.)

Any extra costs that arise after checkout (for remote access, limited access, or special handling) will be discussed with you before proceeding.

Delivery times depend on:

• Product availability and processing time
• The carrier and service level selected
• Distance and any carrier delays (weather, peak season, etc.)

We provide estimated timeframes but cannot guarantee specific delivery dates unless explicitly stated in writing for a particular order.

For freight and large shipments, always:

• Inspect the packaging and product for visible damage before signing
• Note any damage or shortages on the delivery receipt or bill of lading
• Take clear photos of any damaged areas and packaging
• Contact us promptly if there are issues

Signing “clean” without noting damage can make freight claims more difficult.

Returns for lifts and heavy equipment are more complex than small parcels. In general:

• Items must be new, unused, uninstalled, and in original packaging to be considered.
• Returns must be authorized in advance.
• Freight return shipping can be expensive and is often the customer’s responsibility unless the return is due to our error.
• Restocking fees may apply, especially for heavy or special-order products.

See our Returns & Refunds policy for full details.

In most cases:

• If you’re returning an item due to a change of mind, ordering the wrong product, or similar reasons, you are responsible for return shipping.
• If the return is due to our mistake (for example, wrong item shipped) and reported promptly, we’ll work with you on a solution, which may include arranged return shipping or other options.

Once an authorized return is received and inspected:

• Refunds are generally issued to the original payment method.
• The amount may be reduced by restocking fees, original shipping, and return shipping (where applicable).
• Processing times vary; once we issue the refund, it may take several business days to appear on your statement.

In most cases, warranty coverage is provided by the product’s manufacturer, not Dunfer directly.

• Manufacturer warranties cover defects in materials or workmanship under normal use.
• Terms, coverage periods, and conditions are set by the manufacturer.
• Dunfer can help you start the process and provide documentation, but we don’t override or extend manufacturer warranties.

If you suspect a warranty issue:

1. Gather your proof of purchase (order number or invoice).
2. Collect product details (model, serial number if available).
3. Take clear photos or videos showing the issue.
4. Contact us with all of the above.

We’ll help guide you toward the appropriate manufacturer process or support channel.

Usually, manufacturer warranties cover the product or parts, not:

• Installation or removal labor
• Travel time or on-site service costs
• Freight or shipping costs for returns in some cases

Always review the specific warranty terms for your product.

Often, yes—subject to availability and manufacturer support.

• You may be able to purchase replacement parts through us or directly from the manufacturer.
• Labor and all associated costs for repairs outside of warranty are your responsibility.

All repair work should be done by qualified technicians.

We use reasonable technical and administrative safeguards to protect your personal information and work with reputable payment processors.
