Universal Construction Key - Multi Valve Tool - Silver

2-piece universal zinc alloy construction key with nickel-gloss coating, including built-in cylinder gauge (22–75 mm), special PZ push-in lock nose, three square key heads (6/7/8 mm) and four-in-one key head for square/triangular/round holes — ideal for electrical switch cabinets, gas/water/electricity meters, lifts, heating valves, and ventilation grilles.

·Multi-Functionality: Combines building key, architect's key, switch cabinet key, and cylinder key in one compact tool — no more switching between tools when servicing electrical switch cabinets, gas/water/electricity meters, lifts, heating valves, or ventilation grilles; eliminates delays caused by mismatched keys for PZ socket locks or standard square/triangle/round openings.

·

·Precision Measurement: Integrated cylinder length scale (22–75 mm) enables direct, repeatable measurement without external calipers or rulers — solves the common of inaccurate cylinder fitting during lock replacement or maintenance on PZ socket locks, especially where profile cylinders are not used externally.

·

·Robust Construction: High-grade zinc alloy with nickel finish ensures exceptional wear resistance and long-term durability under frequent use on construction sites and technical service assignments — withstands repeated torque on heating valves, ventilation grilles and switch cabinet mechanisms without deformation or coating wear.

·

·Effortless Access: Designed specifically for maintenance technicians who need rapid, secure entry to protected areas — reduces physical strain and time pressure during emergency interventions in lifts, utility meters or electrical enclosures, supporting calm and confident operation even in tight spaces.

·

·Trusted Reliability: Eliminates uncertainty when working with various locking systems across buildings and infrastructure — gives technicians peace of mind knowing one key handles PZ socket locks, square (6/7/8 mm) actuation points, and non-standard shapes, reducing tool clutter and improving job-site organization.
