Glynn-Johnson 101H-SPBLK – Frequently Asked Questions
1) What are Glynn Johnson 100 Series heavy duty concealed overhead door holders used for?
These units hold doors in the open position while remaining hidden from view. They mount above the door frame and engage automatically when the door opens to a preset angle. Common applications include commercial entrances, institutional doors, and areas requiring hands-free door holding.
2) What door weights can the 100 Series handle?
The 100 Series is rated for heavy duty applications with doors up to 200 pounds. The exact weight capacity depends on door width, frame construction, and mounting conditions. Verify your specific door weight and dimensions before ordering.
3) Are these door holders handed or universal?
Glynn Johnson 100 Series holders are typically handed for left-hand or right-hand doors. Handing is determined by standing on the pull side of the door. Order the correct hand to ensure proper operation and engagement angle.
4) What finishes are available for the 100 Series?
Standard finishes include aluminum, dark bronze, and other architectural finishes to match door hardware. The concealed design minimizes visible components. Consult the manufacturer specifications for available finish options.
5) Do these door holders meet fire code requirements?
Many models include automatic release mechanisms that comply with fire safety codes. The holder releases when the fire alarm activates or power is interrupted. Verify local code requirements and specify fire-rated models when required for your application.
6) What components are included with the door holder?
Typical packages include the main holder body, mounting brackets, door-mounted catch plate, fasteners, and installation template. Electrical components for automatic release may be separate. Review the specific model specification for complete component lists.
7) How is the 100 Series door holder installed?
Installation requires mounting the holder body above the door frame and the catch plate on the door top rail. Use the manufacturer template for precise positioning. Solid blocking above the frame is often necessary. Electrical connections are needed for automatic release functions.
8) Can the hold-open angle be adjusted?
Most 100 Series holders allow adjustment of the engagement angle and holding position. Adjustments are made through alignment of the catch plate and holder mechanism. Follow manufacturer instructions for proper adjustment procedures to ensure reliable operation.
9) What maintenance do these door holders require?
Periodic inspection of mounting hardware, catch plate alignment, and release mechanism operation is recommended. Clean debris from moving parts and verify electrical connections remain secure. Test automatic release function monthly in fire-rated applications.
10) Are there related Glynn Johnson door control products?
Glynn Johnson offers various door hardware solutions including surface-mounted holders, electromagnetic holders, and door coordinators. The 100 Series represents their heavy-duty concealed option within a broader product family.
11) What are alternative solutions to concealed overhead holders?
Alternatives include surface-mounted door holders, electromagnetic holders, and kick-down stops. Each has different aesthetic, functional, and code compliance characteristics. Consider visibility requirements, door weight, and release method when selecting the appropriate solution.
12) What frame and door construction is required for installation?
Installation requires solid mounting surfaces above the door frame and adequate door top rail for catch plate attachment. Steel frames may need reinforcement blocking. Verify frame construction can support the holder loads and door operating forces before installation.
