All of our sliding door hardware lines, door pulls, and accessories are available for order through our website. Click here for more detailed information on the ordering process.

We encourage you to reach out with any questions!  Our website is designed to be a powerful resource, but not a substitute for direct support whenever that is needed. 

To select the correct track length in our product builder, simply multiply the width of your door panel by two.  This is a good general rule.  For a more precise calculation, here is the formula:

When complex configurations are involved, Krownlab may provide drawings to aid in confirming track length and drill pattern.  This is typically done within 1 - 2 business days of the order being finalized. The fabrication drawing process includes two rounds of revisions at no charge. Additional revisions are available for $50 each. Production lead time will begin once the drawings are approved.

When an order is placed, we will email an order confirmation that includes an estimated ship date. Our Quick Ship program has most orders shipping within 3 business days! Production lead time depends on the quantity purchased and the particular configuration of your order.

Krownlab offers a standard 10% trade discount to professionals within the design and construction industry. We can cover credentials quickly by phone or email. Clear, simple, transparent. 

We do have a standardized volume discounting policy for orders over 10, 20, 50, or 100 units. To receive a quote for purchasing in volume, contact Krownlab Support.

We offer most of our sliding door hardware systems in three configurations: Single, Bi-Parting, and Bypassing.

Appropriate panel clearance depends on which hardware system you choose.  We publish specs for all of our systems on our Downloads page. For installations outside of the panel clearance ranges outlined, contact Krownlab Support.

Krownlab hardware can be installed into framed walls, glass walls, concrete walls, and steel beams. Learn more.

We recommend that your door panel be at least 2” to 4” wider than your door opening. (If you have a bi-parting application where two doors will cover one door opening, we recommend that the combined total width of the doors be at least 2” to 4” wider than the door opening.)

In addition to limiting the light and noise that will pass through when the door is closed, this will allow your bottom guide solution to stay engaged during the full travel of your door. 

Wood blocking is structural material installed between studs, into which our hardware will be mounted. We do not recommend installing our hardware directly into studs--it requires an enormous amount of accuracy, and they often aren’t in the correct location anyway.

For remodels, you will need to carefully cut a rectangular opening in the wall, install horizontal blocking at the correct height, and re-install drywall in the opening before proceeding with the hardware installation. For new construction, specify horizontal 4” x 4” blocking between studs at the correct height. The height of your blocking will vary depending on the product and accessories you select, but is generally 2.5” higher than the height of your door panel. Reference our installation instructions for more information.

All sliding doors need some kind of bottom guide. Bottom guides are mounted in the finished floor and are always hidden by the panel (wood doors) or engaged with the panel (glass doors). Bottom guides ensure consistent door travel, keep the door plumb, and prevent door panels from swinging out from the track and possibly dislodging. Also, a door panel in a sliding door system naturally wants to hang slightly angled toward the wall. A bottom guide prevents door panels from rubbing against and possibly damaging walls or baseboards.

We include a bottom guide with every sliding door hardware system we sell. However there is some variation in bottom guides, depending on your aesthetic preference and the kind door panel you’re working with. Learn more

Yes. Because Axel's track can be easily cut and drilled in the field, its door travel can be quickly modified. Learn more.

You’ll want at least 8.25” of clearance for Baldur and at least 7” of clearance for all other systems. Axel requires the least amount of clearance at 5".  For more detailed dimensional information, head over to our Downloads page for technical drawings and installation instructions.

We have engineered our bypassing sliding door hardware systems to be clean and uncluttered. Find out how.

We offer three families of door pulls: Ebba, Olav, and Inger. Each have distinct features to consider when choosing the right door pull for your project. And with multiple finishes available for each, no matter what your project calls for, there is the perfect Krownlab door pull solution. Here's what to consider.

Your sliding door travel is controlled when the trolley hits a door stop attached to the track or the door panel impacts a bottom stop attached to the floor. You can employ either method, or use both. Find out how both of our stopping systems work here.

Trust us, we would love to. But our engineers won’t let us release a product that can’t withstand a minimum standard of 15,000 open-and-close cycles, and we can’t find a powder coat or paint finish that fits the bill. We’ve tested every surface finish that we could get our hands on--including some of the most stringent military spec finishes--and not a single one made it past 3,000 cycles without flaking, chipping, or showing significant signs of wear. Sometimes we think our engineers are a little over-concerned with perfection, but then again, that’s why we hired them.

We don’t offer a quieting mechanism, because our products are engineered to be inherently quiet. The sound that your sliding door hardware will make depends bit on the weight and material of your door panel, the construction and insulation of your wall, and the Krownlab line of hardware you choose. 

We do! You can configure bypassing systems for Oden, Baldur, Loki and Rorik on their quoting pages.

We do not currently offer a solution to stack three panels in front of each other. 

Krownlab makes high-performance products. This influences the material grades we use. We therefore primarily use 300 & 400 series of Stainless Steel. These grades are commonly used in other high-performance products such as knives and tools. It is important to remember that Stainless Steel is not “rust proof”.  It is “corrosion resistant”, and will rust in corrosive environments over time. Even a high-grade Stainless Steel product will rust in corrosive environments. Cleaning products containing any type of Chloride will make all 300 & 400 series materials corrode quickly. Mild soap is the ONLY cleaning product that is safe to use around Stainless Steel. Boeshield is a very popular rust preventative coating that dries like a wax. It can be wiped off, or left on for maximum protection. It is available at on-line retailers such as Amazon.
