Cylinder Kits for panic bars exit devices EN 1125 / EN 179 Outside Trims 

Cylinder kits enable controlled re-entry from the safe side when paired with outside trims on EN 1125 panic bars and EN 179 emergency exit devices. EKIN supplies euro profile cylinders in common lengths and keying plans, with guidance on fit, security options and fire-door approvals. 

What’s in a cylinder kit?

A matched euro profile cylinder with keys, fixing screw and any required cam/retaining parts for your outside trim. Kits are specified by profile, length, function (e.g., key–key, key–thumbturn) and keying plan.

Fit & compatibility (quick checks)

• Device type — rim / vertical-rod / mortise; choose the cylinder/trim set listed for your device family.

• Door thickness & escutcheon — confirm cylinder length so the plug sits flush with the trim (no over-projection).

• Handing & through-fix — verify orientation and fixing centres of the trim.

• Frame/clearances — ensure the cylinder/trim does not foul the frame or seals.

Cylinder lengths & profiles

• Standard euro profile sizes (e.g., 30/30, 35/35, 30/40), with extended options for thicker doors.

• Choose key–key where controlled locking is needed on both sides (if permitted), or key–thumbturn for a quick internal release on the safe side.

• For mortise devices, use the mortise-compatible cylinder/trim specified by the manufacturer.

Keying plans (KA / MK / project sets)

• Keyed Alike (KA): multiple doors use the same key.

• Master Key (MK): individual keys per door + one master that opens all.

• Project packs: we can supply grouped sets (e.g., zones/floors) and a schedule for handover.
  Tell us your key count and future expansion needs; we’ll design the plan.

Security & fire-door notes

• Security options: anti-pick / anti-drill / anti-snap cylinders available.

• Fire-door compatibility: match the cylinder/trim approval to the door certificate; use the specified fixings and escutcheons.

• Keep an inspection record of operation, fixings and signage.

FAQ (Cylinder Kits)

Q1: How do I choose the correct cylinder length?
Measure door thickness + escutcheon stack and choose a length (e.g., 30/30 or 35/35) that keeps the cylinder flush with the trim.

Q2: Key–key or key–thumbturn?
Use key–key where policy requires keys on both sides; use key–thumbturn for quick internal release on the safe side (subject to your risk assessment and local rules).

Q3: Are these cylinders fire-door compatible?
Many are, but always match the cylinder + trim + fixings to your door’s fire certificate.

Q4: Can I get cylinders keyed alike or on a master key system?
Yes—provide a keying schedule (doors/zones/quantities). We’ll design KA/MK sets and supply a handover record.

Q5: Do you supply anti-snap/anti-drill options?
Yes. Tell us your security requirement or insurance standard and we’ll specify a suitable cylinder model.

Send device family (EN 1125/EN 179), outside trim type, door thickness, preferred function (key–key/key–thumbturn), keying plan and photos. We’ll propose a matched cylinder kit with an itemised price in £.
