KLT box

Examples of various types of KLT boxes

Parameters of individual types of KLT containers

Each KLT box type is marked with a four-digit code that indicates:

External dimensions (length x width): The first digit in the code indicates approximate external dimensions in centimeters. These dimensions are multiples of a standardized grid compatible with Euro pallets (1200 x 800 mm).

• 3x = 300 x 200 mm
• 4x = 400 x 300 mm
• 6x = 600 x 400 mm
• 8x = 800 x 600 mm

External height: External height: The last two digits in the code (e.g., 14, 15, 17, 28, 29, 32) indicate the approximate height of the box in centimeters.

It may also contain information about the construction type:

Type of construction: The designation before the numerical code (e.g., R-KLT, RL-KLT, C-KLT) indicates the box’s construction type, affecting its strength, weight, and other properties.

• R-KLT (Reinforced-KLT): Reinforced construction. These have solid walls and a base reinforced with ribs and drainage holes. Suitable for heavier loads and automated systems.
• RL-KLT (Reinforced, Light-KLT): Lightweight reinforced construction. They have a smooth but sturdy base without pronounced ribs, ideal for smaller and lighter parts. Also adapted for automated handling.
• C-KLT (Classic-KLT): The original version of KLT boxes. Very robust double walls and reinforced base providing high strength.

Types of KLT box designs in detail

RL-KLT (Reinforced Light-KLT)

• Characteristics: Lightweight version of KLT boxes. The term “Light” refers mostly to the base design and thinner walls than overall strength, which remains very high.
• Base: Smooth base with minimal supportive ribs. Optimized for automated conveyors and warehouses where smooth movement without jamming is needed. Smooth base reduces risk of parts getting stuck or damaged on conveyors.
• Walls: Solid but generally thinner than C-KLT. Despite thinner walls, designed to meet high load capacity and stacking stability standards.
• Usage: Ideal for transport and storage of smaller and lighter parts such as electronic components, fasteners, or small metal pieces. Often used in automated warehouses and logistics centers emphasizing speed and smooth flow.
• Main advantage: Smooth base ideal for smooth movement on conveyors.

R-KLT (Reinforced-KLT)

• Characteristics: Reinforced and more robust type of KLT boxes. “Reinforced” mainly relates to the base designed for high load capacity and durability.
• Base: Distinct integrated ribs (often ladder or cross-shaped) for extreme strength and stability. Can bear much heavier loads and resist deformation. Drainage holes in corners allow water runoff (e.g., when washing boxes).
• Walls: Stronger and often thicker than RL-KLT walls. Designed for maximum strength and durability.
• Usage: Used for transport and storage of heavier parts like stamped metal components, engine or gearbox mechanical parts. Important where handling equipment is often used and high durability is required.
• Main advantage: High load capacity and durability for heavy loads and tough conditions.

C-KLT (Classic-KLT)

• Characteristics: Original and most robust KLT box version. “Classic” refers to the original design still considered a standard for maximum strength and part protection.
• Base: Very strong and massive construction with integrated ribs and drainage holes, similar to R-KLT but often with even thicker walls and ribbing.
• Walls: Double walls (outer and inner connected by posts) creating a hollow profile that significantly increases box strength and stability, protecting parts from side impacts.
• Usage: Used where critical protection of parts and high load capacity are essential, e.g., for transporting sensitive but heavy components or long-term storage in demanding industrial conditions.
• Main advantage: Maximum strength, durability, and protection of contents thanks to double walls.
