Astec Fitting b.400 Barn Door Hardware

One of Astec's most popular solutions for sliding door hardware, the simplicity of the b.400 belies a flexibility and level of technical sophistication that few other systems can provide. 

Sliding Door Hardware: Wheels

It really couldn't be simpler. Circular brushed stainless steel wheels clamp through both sides of a glass or wood door panel and ride in parallel grooves in the floor. The amazing thing is that with two wheels, this floor-bearing barn door hardware system, like the astec b.410, can carry a door leaf weighing up to 1760 lbs. (800kg.) That's comparable to a 1/2" glass door that's 25ft long and 10ft high (or anything less than that).

When you want to avoid the money and hassle of installing steel or other additional structure to support a large sliding door, the floor-bearing wheels of the astec b.400 sliding barn door hardware can provide smooth and easy movement for panels of nearly any thickness.

For wood door applications, the wheels can be installed mortised flush to the surface for a clean and unique option for large pocket doors.

Sliding Door Hardware: Floor Track

Here's where the options get interesting. Astec offers two standard track materials for the astec 400:

    1. High density polyamide track in gray or black. This easily-machined material can be laid flush to the finished floor to create a threshold that is only 2" wide (material is .59" thick).
    2. Machined stainless steel track which we often see specified for bathroom and shower applications. 

      Astec will machine tracks for multi-panel or telescoping installations.

      Now, as long as the material that the wheels roll on is dense enough to withstand the weight of the doors passing, one could use anything to provide a track for the wheels. Most often, an installer will simply route the 5mm x 7.5mm grooves out of oak or other hardwood to match the adjacent flooring.

      *See the Astec b.400 Technical Document in the downloads section for groove and spacing details for different configurations.

      Sliding Door Hardware: Ceiling Track

      The standard 20x40mm aluminum ceiling profile is all that's needed to guide the panel. This aluminum profile can be surface or flush mounted to the ceiling. 

      Two door stops are installed on either end of the ceiling guide. They have been included in the set pricing.

      In order to set the panel on the track, the glass panel must be machined to allow the installers to lift the glass up 5mm (.2") into the ceiling guide.

      Sliding Door Hardware: Closer / Damper *NOW AVAILABLE*

      Instead of the standard stops, Astec has recently added the option of a high-performance automatic closer and damper. The capacity for this closer is 440 lbs. (200 kg.). The closer requires a different ceiling guide than the one for the sets specified here.

      In order to give you ballpark pricing for common installations, we have provided set pricing based on:
