21B inch handheld hard case

The Professional Companion for Large Items

This 21B inch handheld hard case is designed for professional applications where items are large but thin. While retaining the 21-inch case's length and width adaptability, it optimizes depth for focused surface protection. The case body is designed and manufactured in our own factory, using high-quality, impact-resistant, and long-lasting PP plastic. For designers, electronic engineers, photographers, or users who need to carry large-format sensitive items, this is an ideal choice for achieving lightweight design and ample surface space while ensuring comprehensive protection.

Product Features and Applications

Optimized Slim Design: The internal depth is optimized for flat items, providing ample protection while reducing unnecessary volume and weight, making it easier to carry and store.

Customizable Internal Layout: This 21B inch handheld hard case can be equipped with additional foam; the top lid can be fitted with wavy eggshell foam, and the bottom lid with tear-off checkered foam; custom EVA foam can also be die-cut into any shape. Creates a perfectly fitted and secure space for tablets, drawings, circuit boards, panels, and other items, preventing scratches and bending.

Strict Quality Process: Every batch of our 21B inch handheld hard cases undergoes a rigorous quality control process. This includes raw material inspection, dimensional checks during production, and a final IP67 waterproof and dustproof test to verify the integrity of the seal before shipment.

Use Scenarios:

Drawings and Documents Transportation: Securely store and carry large-format documents such as architectural drawings, engineering blueprints, and posters.
Electronic Product Protection: Protect laptops, tablets, large circuit boards, or display panels.
Photographic Works: Transport photographs, paintings, or other artworks that require flat protection.

Product Advantages and Comparison

Why is the WEISHUO’s Case the Better Choice?
High-Quality PP Material: Designed for high hardness and excellent impact resistance, ensuring sufficient structural strength and long-term durability despite its relatively thin profile.
Rugged Hardware: Featuring reinforced locking points and durable hinges, it can withstand thousands of opening and closing cycles.
IP67 Sealing Guarantee: The precision-molded lid with continuous sealing grooves provides a consistent and reliable waterproof and dustproof barrier, effectively protecting moisture-sensitive documents or electronic products.

Usage, Care, and Maintenance Instructions:
Ensuring Optimal Seal: Before closing, ensure the lid seal is clean and free of foreign objects, and that stored items are flat and will not obstruct the lid's closure.
Cleaning: Clean the exterior with mild soap and water. Avoid using strong chemicals or abrasive cleaners that may damage surfaces or seals.
Storage: It is recommended to store the case flat and avoid placing heavy objects on top to prevent potential deformation.

FAQ

Q1: How should I choose between the 21-inch standard model and this 21-inch slim model?
A1: The choice depends on the maximum thickness of the items you need to store. If your items are primarily flat, less than 80mm thick, and you want a lighter, more space-saving case, then the slim model is a better choice. If you need to store thicker or taller items, you should choose the standard model.

Q2: Does the slim design mean reduced protection or strength?
A2: No. The protective performance (IP67 rating) is exactly the same as the standard model. In terms of strength, we have optimized the material distribution and internal structure to ensure that the thin enclosure has sufficient pressure and impact resistance within its designed load-bearing range to meet the needs of its target application scenarios.
