Stanley Dura-Glide–class sliding door operator control

Identity

Aliases

• Stanley Dura-Glide controller (common_name)
• Stanley Access Dura-Glide control board (oem)
• 314321 (oem) — Stanley Replacement Parts Book (Oct 2024): “iQ CONTROLLER DUAL KIT” for Dura-Glide 2000/3000 headers. Current OEM kit identity — still verify generation vs older MC521 boards in the field.
• iQ controller (Dura-Glide) (oem) — Current Stanley/Allegion generation inside Dura-Glide packages. Not a separate AutoDoor Atlas family page — identify as Dura-Glide + iQ kit/label.
• R185000SL (revision) — DCUSA 2016 Dura-Glide 2000/3000: “MC521, SLIDE, DIGITAL CONTROL.” Older/surplus generation vs 2024 iQ kits. Search cue only.
• MC521 (revision) — Stanley digital control family seen in aftermarket Dura-Glide (slide), cart (R185000CT), and other Stanley lines. MC521 is not one interchangeable board across slide/swing/cart.
• R312891G (revision) — DCUSA 2016 “PC CONTROL - GREY” under Dura-Glide 2000/3000. Photograph color + sticker; tan variants also listed (R312891T).
• R516098 (revision) — DCUSA 2016 “DURAGLIDE INTERFACE BOARD (NEW STYLE)” vs old-style R313383. Interface boards are not the main logic board.
• R313383 (revision) — DCUSA 2016 Dura-Glide interface board, old style. Commonly confused with the main control.
• Stanley sliding door computer (common_name) — Vague; still used in search — disambiguate in content.

Revision notes

Dura-Glide packages span years of production. 2024 OEM replacement for DG 2000/3000 headers is iQ kit 314321; 2016 aftermarket stock still listed MC521 (R185000SL), grey/tan PC controls, and old/new interface boards (R313383 / R516098). Treat lookalike boards as unverified without label and connector evidence. iQ is a generation, not a separate catalog family on this site.

Labels & connectors to capture

• Stanley Access Technologies / Stanley branding on control assembly
• Dura-Glide or related model references on plates or stickers
• Sticker or kit numbers: 314321 (iQ dual kit), R185000SL / MC521, R312891G/T, interface R516098 or R313383
• Motor and breakout connectors particular to the operator generation
• Separate activation device cables (not part of the logic board unless stated)

Common mistaken names

• Stanley “magic” / other series controls listed as Dura-Glide
• BEA or other activation sensors titled as Stanley controllers

Fitment & compatibility

Commercial sliding automatic doors in the Stanley Access Technologies Dura-Glide family and closely related sliding packages. Confirm plates on the operator header and control enclosure.

Voltage: Package-specific. Use on-unit labeling and Stanley documentation for the exact control; do not generalize from a single listing photo.

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.

• Dead core / unknown working

  Numeric range not published yet — see notes · confidence: low · as of 2026-04-01

  Cores with zero readable labeling are near scrap to many rebuilders; labeled Dura-Glide controls retain more inquiry interest.

  Provenance: Qualitative guidance only; no published sold-comp table on this page.

• Rebuilt / refurbished

  Numeric range not published yet — see notes · confidence: low · as of 2026-04-01

  Rebuilt claims need who rebuilt it, what was replaced, and what test was performed — otherwise treat as unknown used.

  Provenance: Process guidance for evaluating rebuilt listings; prices not asserted.

• Commonly confused with

  Stanley Magic-Force–class swing door operator control

  Magic-Force is a Stanley swing-operator family; sellers often title either as a generic “Stanley door control,” which mixes sliding and swing searches.

• Same manufacturer

  Stanley Magic-Force–class swing door operator control

  Both are Stanley Access Technologies operator control families; confirm sliding Dura-Glide vs swing Magic-Force on operator plates.

• Similar family

  Besam UniSlide / sliding-door operator control family

  Peer commercial sliding-operator control role under a different OEM; use branding and package plates, not board shape alone.

• Used vs rebuilt: what buyers should verify

Curated field notes

Dura-Glide is a high-recognition Stanley sliding family in the field. Marketplace titles often say “Stanley door board” without Dura-Glide, Magic-Access, or other family cues, which wastes both buyer and seller time. Curated value here is teaching people to capture the family name, the control label, and the difference between the operator logic assembly and bolt-on activation devices.
