The ECS Hardware line at Keyless City delivers hard-wearing, commercial door hardware that holds up under real-world use. From narrow-stile hook-bolt locks to combo door sets, ECS brings durable solutions for installers and locksmiths who need reliable access gear for storefronts, offices, apartments, and mailboxes. 

Collection Overview

The ECS Hardware Collection covers three core areas:

• Narrow-stile hook-bolt lock bodies
• Premium mailbox and perimeter locks
• Combo entrance door locksets (knob + deadbolt)
  
  

These products are crafted from corrosion-resistant metals, built to ANSI Grade standards, and ideal for both residential and light commercial applications. If you install locks in apartments, condos, or commercial entryways, these ECS items are worth checking out.

Narrow-Stile Hook-Bolt Lock Body

This premium Narrow‑Stile Hook‑Bolt Lock (1–1⁄8″ backset) is designed for sleek aluminum or steel storefront doors. It includes two faceplates—oil rubbed bronze and aluminum finish—so it matches your frame aesthetic. The bolt is a 5‑ply laminated steel design with a concealed hardened pin to stop hacksaw attacks. Zinc‑plated metal resists corrosion. You can install it with a standard mortise cylinder and thumb-turn—perfect for retrofits or tight-jamb situations 

Premium USPS Mailbox Lock – Clockwise HC1 Keyway

Built for apartment mailboxes or compactor doors, this heavy-duty USPS HL1 mailbox lock is keyed different, finished in bright nickel. It features a precision chrome-plated plug and cams, rated for 1,000 key changes, and built to National D4292 (Ilco 1069LB) equivalence for strong security in communal settings. Ideal for property managers or installation businesses.

Combo Knob + Deadbolt Entrance Sets

The Durable Combo Lockset delivers a Grade 3 knob and deadbolt combo with a single removable Key-In-Knob (KIK) cylinder—available in KW1 or SC1 keyway. Backed by stainless steel construction and reliable ANSI F109 functionality, these sets come keyed differently and include four matching brass keys, so you can install an entrance set from the same box.

Built to Withstand Real Install Conditions

ECS Hardware is built for locksmiths who need gear that’s more than decorative:

• All-steel construction resists forced entry
• ANSI grade ratings ensure commercial-quality toughness
• Corrosion-resistant finishes handle salt, rain, and traffic
• Standard keyways (KW1, SC1) simplify keying services
• Pre-keyed sets speed up installations and reduce inventory errors
