ABH 2100--US28 – Frequently Asked Questions

1) Which ABH electromagnetic lock models does the 20020 armature head assembly fit?
The 20020 armature head assembly is the standard-door armature for ABH 2100, 2300, 2400, 2600 and 2700 electromagnetic door control systems. You pick the model when you order, so the head you receive is built for the series you already have on the opening. If your ABH magnet is outside those five series, this is not the right armature.
2) What does the 1-5/8 inch projection on the ABH 20020 armature mean for my door gap?
1-5/8 inches is how far the armature head stands off its mounting point, and it is what sets the armature face against the magnet face. Order the projection that matches what came off the door. A different projection changes the standoff and the armature no longer seats flat on the magnet, which is where holding force is lost.
3) Is the ABH 20020 a whole magnetic lock or just the armature?
Just the armature head assembly, the door-mounted plate the electromagnet pulls against. It is sold as a replacement part, not as a lock. The magnet body, power supply and release device stay as they are; this is what you order when the armature is the damaged or missing piece.
4) Is the ABH 20020 armature Buy American Act compliant for a government job?
BAA qualified, yes. For federal, municipal, public school and other publicly funded work where Buy American language is on the spec, the 20020 armature head clears that requirement, and it is rated for commercial use rather than residential.
5) What finishes does the ABH 20020 armature head come in?
Eight finishes: painted aluminum, painted brass, painted bronze, painted black, painted dark bronze, satin aluminum, bright stainless steel and satin stainless steel. All eight are offered against each of the 2100, 2300, 2400, 2600 and 2700 models, so a property manager standardizing a run of openings can hold one finish across every door regardless of which ABH magnet series is on it.
6) My magnet is mounted on a frame that sits proud of the door, so the armature will not reach. What do I use?
A plain standard-door armature will not solve a mounting offset. The 20020 is the standard-door head, built for a flush condition at a fixed 1-5/8 inch projection. Where the geometry of the opening puts the armature out of line with the magnet, an offset strike is the part that closes the gap, such as the Securitron AOS armature offset strikes.
7) Can I fit an ABH 20020 armature to a glass door or a Codelocks glass door lock?
No. The 20020 is a standard-door armature for ABH 2100 through 2700 electromagnetic systems and nothing else. Glass door hardware takes its own purpose-built parts, for instance the Codelocks glass door strike box for the CL4000 and CL4500 glass door locks. Matching an ABH armature to a glass opening is not something to attempt.
8) What do I have to specify when ordering an ABH 20020 armature head?
Two things: the ABH model the armature is going onto (2100, 2300, 2400, 2600 or 2700) and the finish. Projection is fixed at 1-5/8 inches on the 20020, so that is not a choice, it is a condition your opening either matches or does not. Get the model right first, then match the finish to the rest of the door hardware.
9) Will a glass door strike box work in place of an ABH 20020 armature head?
No - they solve different problems. The ABH 20020 is an armature head assembly with 1-5/8 inch projection that pairs with the magnet on an ABH 2100, 2300, 2400, 2600 or 2700 electromagnetic door control system. The Codelocks CL4000-RSB is a glass door strike box for use with CL4000 or CL4500 glass door locks, so it serves a mechanical glass door lock, not an electromagnet. An electromagnetic opening needs the armature head matched to its magnet series.
10) Do I need to key or cylinder anything when replacing an ABH armature head?
No keying at all. The 20020 armature is a non-keyed component with no cylinder, no keyway and no lock function; holding and release are handled electrically by the magnet and whatever is controlling it. Nothing on the armature side needs to be pinned or keyed to a facility system.
11) Where can I get the mounting template and cut sheet for an ABH door armature?
ABH publishes both. The electromagnetic door armatures and extensions template covers the mounting layout, and the parts cut sheet for door armatures, extensions, electrical boxes, wall covers and wall portions gives the component detail. Both PDFs are carried alongside the 20020, plus the ABH full line catalog for the wider 2100 through 2700 range.
12) Is an anchor plate the same thing as an armature head, or do I need both?
They are different parts. The Trimco 1268 anchor plate is a 3-1/2 inch diameter plate, while the ABH 20020 armature head assembly carries a 1-5/8 inch projection and is the steel face the ABH 2100, 2300, 2400, 2600 or 2700 magnet actually holds against. If the job is replacing the piece that mates with an ABH electromagnet, the 20020 head assembly is the part to order.
