Product Description

Smoke Detector Alarm Hollow Wall Mini Wing Anchor Nylon Ceiling Mounting

Product Description

This Nylon Hollow Wall Mini Wing Anchor is a lightweight ceiling-mount fastening solution specifically designed for smoke detectors, carbon monoxide alarms, security sensors, motion detectors, and small ceiling-mounted safety devices on plasterboard and gypsum board surfaces. Each anchor includes a 5mm diameter nylon mini expanding wing plug pre-matched with an M3.5 x 30mm zinc-plated self-tapping screw, providing secure overhead anchoring for lightweight safety equipment.

The installation follows the straightforward hollow wall anchoring principle: drill a 5mm hole at the ceiling mounting position, insert the nylon plug until the flange is flush with the ceiling surface, position the detector mounting bracket, and drive the M3.5 screw upward into the plug. As the screw advances, it compresses the nylon body and triggers the mini-wings to fold outward behind the plasterboard. These wings create a positive mechanical lock on the rear side of the ceiling board, securely holding the safety device against gravity without relying on hole-wall friction that can deteriorate over time in ceiling installations.

The nylon material combines excellent toughness with superior aging resistance, ensuring the wing anchor maintains its full gripping force through the entire service life of the smoke detector - often 10 years or more between device replacements. The compact 30mm body length requires minimal rear cavity clearance, making it compatible with the tight overhead spaces typically found in ceiling installations. The nylon plug body is naturally non-conductive, providing an additional safety layer for electrically powered safety devices.

Features

Ultra-Compact Ceiling Profile: The slim 5mm x 30mm plug body requires only a minimal 3mm rear cavity clearance behind the plasterboard, ensuring compatibility with the tight overhead spaces and shallow cavities commonly encountered in ceiling installations. The low-profile flange sits flush against the ceiling surface, allowing the detector mounting plate to be positioned tightly without visible anchor gaps.

Decade-Long Aging Resistance: The PA6 nylon material is specifically formulated for long-term aging resistance, maintaining full wing expansion grip and mechanical integrity through the entire 10+ year service life of smoke detectors and safety alarms. Never becomes brittle, never cracks, and never loses holding force over extended ceiling installation periods.

Non-Conductive Safety Anchor: The 100% nylon plug body functions as a natural electrical insulator between the metal screw and surrounding ceiling material. This provides essential electrical safety when mounting hard-wired smoke detectors and alarm sensors, eliminating any risk of current conduction through the mounting fastener to the ceiling fixture bracket.
