The Maco Rail Inline Espag Window Lock is an ideal security upgrade for homeowners and contractors looking to enhance window safety without the complexity of shootbolt systems. This high-security Reverse Action In Line (R.A.I.L.) mechanism uses twin cams to provide superior resistance against forced entry through sash separation. While it offers excellent security and simple installation, it is specifically engineered for 200mm sash rebate sizes, making accurate measurement essential before selection.

The reverse action ensures that the cams pull in opposite directions, clamping the sash more securely to the frame than unidirectional systems.
No, the Maco R.A.I.L. system is specifically designed to meet PAS 24 security standards without the need for additional shootbolts.
The backset is the distance from the edge of the lock faceplate to the center of the handle spindle hole; this must match your existing window profile.
No, this specific model is engineered for a 200mm sash rebate size. Using it on an incorrect size will prevent proper engagement.
The Silverlook-Evo finish is designed for high corrosion resistance, making it suitable for many environments, though regular cleaning is recommended in coastal areas.
Adjust the eccentric mushroom cams to reduce compression pressure on the weather seal.
Increase the compression by rotating the eccentric cams to pull the sash tighter against the frame.
Clean away any debris in the Eurogroove and apply a small amount of silicone-based lubricant to the cam runners.
Installation of this lock is streamlined due to its one-piece design. Ensure your window features a 12mm or shallow Eurogroove to accommodate the rail. When mounting, align the locking points carefully with the striker plate to ensure the twin cams engage symmetrically. For maintenance, it is recommended to lightly lubricate the moving parts annually with a non-acidic, resin-free grease. Use a damp cloth to wipe the Silverlook-Evo finish to maintain its corrosion resistance; avoid harsh chemical cleaners which can strip the protective coating.
