540 Rim Lock

Model 540 Rim Lock – Product Overview

The Model 540 is a heavy-duty rim lock series designed for markets that demand superior strength and cost-effective flexibility. Its defining feature is the thickened full iron housing, which provides exceptional structural integrity and resistance to forced entry, making it a preferred choice for high-security applications in North Africa and beyond.

Robust Triangle Cylinder Design:
The Model 540 comes standard with a Triangle Cylinder Head, a geometric shape widely perceived as more solid and durable than traditional round heads. For clients seeking an even more premium aesthetic, the lock head can be upgraded to the “Type B” finish, featuring a sophisticated brushed metal treatment that adds a refined, modern touch while maintaining its rugged appearance.

Innovative Deadbolt Options (Cost vs. Quality):
A key advantage of the Model 540 is its flexible deadbolt configuration, allowing customers to balance budget and performance:

• Standard Rectangular Deadbolt: The classic choice for maximum surface contact and traditional security.
• 3-Cylinder Deadbolt: An innovative design featuring three solid steel cylinders. This option significantly reduces material costs while maintaining nearly identical security performance and durability to the solid rectangular block, offering excellent value for money.

Customizable Bolts & Sizing:

• Bolt Materials: The latch bolt, hook bolt, and deadbolt can be customized in Iron, Stainless Steel, Brass, or Zinc Alloy to suit specific environmental conditions or project budgets.
• Sizes: Available in two body lengths: 120mm and 140mm, ensuring compatibility with various door preparations.

Model Naming Convention:
The Model 540 uses a clear coding system to specify configurations:

• Base Model: 540 (Standard triangle head)
• Brushed Finish: 540B (Suffix “B” indicates the brushed “Type B” cylinder head)
• Size Indicator: .12 (120mm) or .14 (140mm).
  • Example: 540B.12 = Brushed head, 120mm length.
• Deadbolt Type: -3M (Suffix “-3M” indicates the 3-cylinder deadbolt; no suffix means standard rectangular deadbolt).
  • Example: 540B.12-3M = Brushed head, 120mm length, with 3-cylinder deadbolt.

Key Configurations:

• Model 540 Series: Housing: Thickened Full Iron.
• Cylinder: Triangle Shape (Standard or Brushed “Type B”).
• Deadbolt Options: Standard Rectangular OR 3-Cylinder (Cost-saving).
• Bolt Materials: Customizable (Iron, Stainless, Brass, Zinc Alloy).
• Sizes: 120mm and 140mm.

Customization options include:

• Housing Strength: Standard thickened iron construction for maximum durability.
• Visual Finish: Upgrade to the brushed “Type B” cylinder head for a premium look.
• Cost Optimization: Select the 3-cylinder deadbolt to lower unit costs without sacrificing security quality.
• Material Selection: Choose bolt materials based on corrosion resistance needs or budget constraints.

The Model 540 combines reinforced construction with smart engineering choices, offering a versatile solution that meets both high-security demands and cost-sensitive project requirements.
