Stanley Bifold automatic door family
Primary identifier: Stanley Bifold · Status: active
System page for Stanley Bifold packages. Owner-listed components (iQ M-Force dual kit 314315, operator 314309, switch 191841, sensors, encoder 314327) are associations to verify by revision — not a claim that every bifold uses every item.
Verified catalog components
Concise catalog entries listed for this family in referenced parts material. They are not a drop-in bill of materials — verify revision and configuration before ordering.
Higher-priority identification
191841 Switch Module Assembly
Listed for M-Force and Bifold in owner material. Verify the switch module against the installed operator generation before ordering.
Used on / associated systems: Stanley M-Force swing operator family
Owner-supplied field knowledge: Owner-supplied field identification list (2026-08-15). Listed for this family in the referenced parts material; verify revision and configuration before ordering.
314309 iQ M-Force Operator
Field name: iQ M-Force operator
Complete iQ-generation Magic-Force / M-Force operator, not a lone PCB. Uses white-face higher-resolution encoder kit 314327. Listed for Bifold in owner material as well — verify bifold revision/configuration; do not assume every bifold uses this operator. Not pre-iQ operator 313852.
Used on / associated systems: Stanley M-Force swing operator family, Stanley Magic-Force–class swing door operator control
Owner-supplied field knowledge: Owner-supplied field identification list (2026-08-15). Also appears in the project research index of the Stanley/Allegion Replacement Parts Book (Oct 2024) and/or DCUSA notes — PDFs are not hosted here. Verify header/operator plates; do not treat a number match as drop-in fitment.
314315 iQ M-Force Controller Dual Kit
Field name: iQ M-Force dual controller kit
Not Dura-Glide 314321; not an MC521 board.
Listed for Stanley Bifold in owner material. Not inferred onto every bifold revision. Distinct from Dura-Glide iQ dual kit 314321. Verify the installed controller face PN and operator plates.
Owner-supplied field knowledge: Owner-supplied field identification list (2026-08-15). Listed for this family in the referenced parts material; verify revision and configuration before ordering.
314327 iQ Encoder & Magnet Kit
Field name: iQ encoder/magnet
Not the main operator controller.
Shared iQ-generation encoder kit. On Magic-Force, pair with operator 314309 (white-face / higher-resolution) and iQ controllers — not pre-iQ operator 313852 black-face encoders. Verify operator generation before ordering.
Used on / associated systems: Stanley Dura-Glide 5200 & 5300 sliding door family, Stanley Dura-Glide–class sliding door operator control, Stanley M-Force swing operator family, Stanley Magic-Force–class swing door operator control
Owner-supplied field knowledge: Owner-supplied field identification list (2026-08-15). Also appears in the project research index of the Stanley/Allegion Replacement Parts Book (Oct 2024) and/or DCUSA notes — PDFs are not hosted here.

Identity
- Aliases
- Stanley bifold door (common_name)
- Stanley folding automatic door (common_name)
- Bifold header (common_name)
- 314315 (oem) — iQ M-Force controller dual kit as listed for Bifold.
- Revision notes
- Bifold revisions vary by header, hangers, bottom guides, and operator generation. Current owner list is iQ/M-Force associated — older bifold openings may use a different control. Research index points at the parts-book Bifold section and the bifold owners manual (not hosted). Verify the installed generation before ordering 314315 or 314309.
- Labels & connectors to capture
- Bifold header / cover identification (not a sliding Dura-Glide plate)
- Controller kit identity: 314315 vs other iQ dual kits (314321 is Dura-Glide, not this kit)
- Operator 314309 and encoder 314327 if present
- Switch module 191841
- Sensor models: SU-100 516669 and Bodyguard-T 700577 when those are the installed devices
- Common mistaken names
- Dura-Glide or M-Force swing openings titled as Bifold
- Horton bifold hardware mixed into Stanley bifold searches
- 314321 Dura-Glide iQ dual kit ordered as if it were 314315
Fitment & compatibility
Stanley Access Technologies bifold automatic entrances. Folding-leaf geometry is distinct from sliding Dura-Glide and from swing M-Force even when some iQ/M-Force components are listed on the same opening.
Voltage: Package-specific. Read the installed controller and sensor labels; do not copy M-Force swing voltage notes onto a bifold header without evidence.

Condition / value guidance
Numeric sold comps are published only when researched. Empty dollar fields mean we chose honesty over filler. Asking prices on marketplaces are not sold comps.
Used — untested
Numeric range not published yet — see notes · confidence: low · as of 2026-08-15
No verified sold-comparable table is published on this page. Asking prices, distributor list, and sold comps are different data kinds and are not inferred from each other.
Provenance: Qualitative guidance only — numeric value fields left null until a verified sold or list source is recorded.
Dead core / unknown working
Numeric range not published yet — see notes · confidence: low · as of 2026-08-15
Unlabeled or mixed-generation cores are hard to place. Readable family plates and encoder/controller generation are the first filter.

Seller guidance
Photograph
- Header showing bifold (folding) geometry, not a slider
- Controller face PN (look for 314315 vs 314321)
- Operator and encoder if included
- Sensor labels if sensors are in the lot
Disclose
- Bifold vs swing vs sliding
- Which of 314315 / 314309 / 191841 / sensors are actually in the box
- Tested vs untested
Title tips
- Stanley + Bifold + component PN (314315, 314309, 191841)
- Do not title as Dura-Glide 314321
Buyer guidance
Common mistakes
- Ordering 314321 because both are “iQ dual kits”
- Assuming every bifold uses 314309 / 314327
- Buying sensors as if they were the controller
Revision differences
- 314315 is the bifold-listed iQ M-Force dual kit; 314321 is the Dura-Glide dual kit — different associations
- Sensors 516669 and 700577 are activation/safety devices, not operator logic
Verify before purchase
- Photos showing a bifold header, not a slider or swing only
- Controller PN readable as 314315 if that is the buy
- Operator/encoder generation if 314309 / 314327 are the buy
- Return path if the bifold revision differs

Similar family
Stanley M-Force swing operator family
314309, 191841, and 314327 are also listed on M-Force. Shared components still need bifold revision checks — not automatic interchange.
Same manufacturer
Stanley Magic-Force–class swing door operator control
Magic-Force controller identification remains on the control family page; bifold uses its own listed dual kit 314315.
Commonly confused with
Stanley Dura-Glide 5200 & 5300 sliding door family
Do not confuse bifold 314315 with Dura-Glide 5200/5300 iQ dual 314321.

Guides
Curated field notes
Bifold packages are easy to mis-title as generic Stanley folding or swing doors. The owner-supplied list places several M-Force / iQ items on Bifold: dual controller kit 314315, operator 314309, switch module 191841, encoder 314327, plus SU-100 (516669) and Bodyguard-T (700577) sensors. Those numbers are recorded as listed for this family in the referenced parts material. They are not inferred onto every bifold revision or configuration. Photograph the header, operator, controller face, and sensors. Do not assume a Dura-Glide 314321 dual kit is the bifold 314315 kit.
