Wood case for single calibration weights — KERN (20 g, unpadded) Wood case for single calibration weights designed to store and transport compact/button 20 g calibration pieces for workshop and laboratory use Wooden case for single 20 g calibration weights Unpadded interior for compact storage Compatible with KERN 337, 347, 357, 367 Tidy storage that supports precise workflows A compact wooden case offers a straightforward method to keep 20 g single calibration weights organised and immediately available. The solid construction provides dimensional stability and a consistently flat base, supporting accurate placement of button/compact weights. By storing individual weights in a designated wooden box, routines for weighing checks and calibration are faster and less error-prone, improving throughput in production environments and quality departments. Secure seating without unnecessary cushioning The unpadded interior is deliberately simple: it minimises movement for small, dense calibration weights and prevents soft linings from contaminating or abrading polished weight surfaces. For button-style weights, this layout ensures a snug fit that limits lateral play while handling, reducing the risk of surface marks that could affect mass values. This design choice benefits technicians who require consistent seating to maintain metrological reliability over repeated use. Compatibility that integrates with existing KERN sets Designed for use with specific KERN single weights, the case accepts models commonly used in verification and routine testing. The clear fitment for KERN 337, 347, 357 and 367 series simplifies kit assembly and replacement logistics, enabling direct integration into existing weight sets and trolleys. Compatibility with standard button/compact forms ensures the box can be used across multiple workflows without conversion or adapters. Practical, durable material for everyday workshop demands Made from wood, the case combines light weight and robust handling; at approximately 0.12 kg, it is easy to carry between benches or to transport with mobile calibration kits. The wooden construction gives a firm enclosure that resists deformation under typical workshop conditions, while remaining gentle on polished metal surfaces. The result is a balance of longevity and gentle contact that supports routine metrology tasks without elaborate maintenance requirements. Simple care and clear handling benefits The absence of soft lining reduces cleaning complexity: surfaces can be wiped and inspected quickly, maintaining a hygienic and professional appearance. The compact footprint and uncomplicated closure make the case a practical choice for busy shops where straightforward, reliable storage is a priority. If further adaptation or fitting details are needed, technical advice is available to ensure the case matches specific operational needs.
