About this item
The Adams Rite 7103A is the body kit for the 7100 Series electric strike - fail secure configuration, compatible with Adams Rite 4500, 4900, and cylindrical locksets with 1/2-inch to 5/8-inch latchbolt projection on aluminum, hollow metal, and wood doors. If you searched "7103a", "adams rite electric strike", "adams rite electric strikes", "d7103a", or "adams rite electric lock" - this is the product.
"D7103A": What This Prefix Means
If you searched "d7103a" - the D prefix is a distributor catalog lookup format used in commercial hardware purchasing systems where "D" precedes the manufacturer model number in order forms, procurement databases, and RFQ documents. D7103A, 7103A, and the full voltage suffix variants (7103A-310, 7103A-340, 7103A-510, 7103A-540) all reference the same Adams Rite 7100 Series electric strike body kit in the fail secure configuration.
What the Adams Rite 7103A Electric Strike Does
This is the content gap across every competing page - none explain the fundamental mechanism in plain language for buyers who are new to electric strikes.
A standard Adams Rite deadlatch (4500 or 4900 Series) has a spring-loaded latchbolt that shoots out when the door closes and retracts when the door is opened. The bolt engages a fixed strike in the door frame, and the auxiliary linchpin deadlocks it to prevent pushing it back with a card. To release, you turn a key or handle from outside.
The 7103A electric strike replaces the fixed mechanical strike in the door frame with an electrified strike that has a movable keeper jaw. When the access control system signals the strike, the keeper jaw pivots - releasing the latchbolt without any mechanical operation of the lock itself. The latch does not retract; the strike opens around it. From the user's perspective outside, the door simply pushes open without a key turn when the strike releases. The lock mechanism is completely unchanged.
"Electrically Unlocked" vs "Electrically Locked": EU vs EL Explained
The 7103A is described as "electrically unlocked (fail secure)." These two terms mean the same thing and both are present because different parts of the industry use different terminology:
"Electrically Unlocked" means the strike unlocks when electrical power is applied - the solenoid energizes to release the keeper. Without power, the keeper is mechanically held closed.
"Fail Secure" means on power failure, the door stays secured - the keeper remains closed, the door cannot be opened from outside without a key. This is fail secure.
This is the correct specification for server rooms, pharmaceutical storage, secure offices, and any application where unauthorized entry during a power failure is the greater risk.
"Electrically Locked" (EL) / "Fail Safe" is the opposite - without power the door opens freely, which is required on egress paths and fire-rated doors. The 7103A-515 is the 24VDC fail safe version if that is your requirement.
Field convertible: The 7103A is field convertible between fail safe and fail secure modes - the mode can be changed at the strike without replacing the unit.
Voltage Suffix Matrix: Every 7103A Variant
The 7103A ships in four voltage variants. The suffix on your order determines the voltage:
7103A-310 - 12VDC, fail secure. DC continuous, silent operation. 0.33 amps draw.
7103A-340 - 12VAC, fail secure. AC intermittent solenoid - produces an audible buzz during operation.
7103A-510 - 24VDC, fail secure. DC continuous, silent operation.
7103A-540 - 24VAC, fail secure. AC intermittent solenoid - buzzes during operation.
Match the voltage to your access control power supply output. DC is always preferred when silent operation is required - hospitals, offices, and any environment where audible solenoid buzz is objectionable. AC strikes are acceptable in mechanical rooms, warehouses, and high-ambient-noise environments. AC intermittent solenoids must not be used continuously - they are rated for momentary energization only.
Body Kit Only: What "No Faceplate" Means for Your Order
The 7103A ships as a body kit only - the strike mechanism, keeper jaw, and solenoid assembly. The faceplate is not included.
Two faceplate formats are available separately for the 7100 Series:
7100 (flat faceplate): For standard jambs where the door closes flush or nearly flush with the jamb edge. Faceplate measures 1-1/4" x 4-7/8".
7101 (radius faceplate): Radiused to match the curved nose profile of the inactive leaf in a pair of narrow stile aluminum glass doors. Order 7101 faceplate when the strike mounts against an aluminum inactive leaf stile rather than a flat jamb.
Faceplate kits (FPK series) cover various lip extension requirements for door thickness variations. The basic 7100 series strike lip is correct for 1-3/4-inch thick doors that close flush with the jamb edge. Where door thickness or jamb geometry differs, specify the appropriate lip extension kit by its last dash number. Lip extensions are not available on the 7101 radius faceplate.
Compatible Locks and Latchbolt Requirements
The 7103A accepts latchbolts from Adams Rite 4500 Series deadlatch, 4900 Series heavy duty deadlatch, and discontinued 4700 Series, plus any cylindrical lockset with a latchbolt projection of 1/2-inch to 5/8-inch. This projection range is the mechanical tolerance the strike keeper jaw can accommodate - outside this range the latchbolt will not reliably engage or release from the electric keeper.
Strike opening: 5/8" x 1-7/16" x 1/2" deep. Keeper jaw: stainless steel. Case: approximately 1" x 3-3/8" x 1-5/8" deep. For use in aluminum jambs, hollow metal frames, and wood frames.
