Medium Wheeled Pull Handle Waterproof & Dustproof Drum Case

I.Product Introduction

II. Core Selling Points

1. Full-perimeter IP67 waterproof and dustproof sealing for all-weather outdoor tour protection: The integrally molded high-elastic sealing rubber ring at the case mouth compresses evenly all around after closing the lid. It blocks rainwater and dust during open-air outdoor performances, outdoor shooting on rainy days and dusty construction sites, preventing rust on metal drum fittings and short circuits caused by dampness in microphones and electronic instruments.
2. Shell with thickened three-dimensional grid anti-collision ribs for impact resistance and resistance to deformation and cracking: Grid-shaped raised reinforcing ribs are integrally molded on all six sides of the case without weak splicing joints. The case will not dent or crack from accidental drops, bumps during loading and unloading, or multi-layer stacking, fully safeguarding internal musical instruments and precision equipment throughout tour logistics transfers.
3. Four universal casters plus concealed retractable pull rod for labor-saving and smooth multi-directional pushing: Four 360° universal casters at the bottom enable flexible steering for easy maneuvering in narrow backstages and corridors. The multi-position concealed metal retractable pull rod on the back fits tightly against the case when not in use, allowing a single person to easily push and transport fully loaded large drum parts.
4. Anti-slip auxiliary side handles on both sides for flexible handling in diverse scenarios: Widened embedded anti-slip handles are symmetrically fitted on the left and right sides of the case and reinforced with multi-layer rivets. They facilitate short-distance manual carrying in cramped vehicle compartments or stage backstages where the pull rod cannot be extended, and their curved grips avoid hand abrasion during prolonged lifting.
5. Two sets of symmetrical heavy-duty latches with anti-theft padlock holes for secure closure: Two sets of widened self-locking spring latches evenly compress the case to maintain sealing, preventing accidental popping open during bumpy long-distance truck transport and shipping transfers. Each latch features a standard padlock hole for locking to protect valuable musical instrument equipment during storage and consignment.
6. Front-mounted air pressure balance relief valve for unobstructed opening across regions without negative pressure: The waterproof relief valve automatically equalizes air pressure inside and outside the case. No negative pressure will form to suction the lid shut during cross-city tours or high-altitude outdoor operations, eliminating the need for forceful prying and enabling effortless case opening at different locations.
7. Extended spacious inner compartment plus customizable integrated lining for partitioned fixation of long musical instruments and equipment: The elongated internal storage space accommodates drum shells, strip lighting fixtures and long detection instruments. A wavy foam set comes as standard, and custom one-piece slotted EVA liners are available with individual cutouts shaped to fit drum parts and instruments, preventing sliding and abrasive scratches during bumpy transportation.
8. Weather-resistant modified thickened raw material for long-term stability in high and low temperature tour environments: Anti-UV and cold-resistant modifiers are added to the raw material to maintain stable toughness across extreme temperatures. The case resists whitening, embrittlement, softening and deformation when exposed to intense summer sunlight outdoors or frigid winter tour venues.
