4. Multiple anti-slip reinforced handles on three sides for flexible movement in confined spaces: A primary anti-slip front handle and symmetrical side handles on the left and right sides are all reinforced via multi-layer mechanical riveting. They allow short-distance hand-carry transport in truck compartments where the pull rod cannot be extended, narrow backstage areas and stairwells. The curved anti-slip grips prevent hand abrasion during prolonged carrying.
5. Multiple synchronous heavy-duty self-locking latches around the perimeter with anti-theft padlock holes for secure closure: Widened and thickened spring latches distributed all around the case compress the case synchronously when shut, eliminating accidental popping open during bumpy long-distance truck transport and logistics handling. Each latch is equipped with a standard padlock hole for added anti-theft protection with padlocks during off-site storage and long-distance consignment.
6. Front-mounted pressure balance relief valve for smooth lid opening across regions without negative pressure jams: An independent waterproof relief valve automatically equalizes air pressure inside and outside the case. No negative pressure suction forms on the lid during cross-city tours or high-altitude field operations, so the case can be opened effortlessly at different locations without prying forcefully.
7. Extra-large heightened and widened storage compartment plus customizable one-piece inner lining for partitioned fixation of complete large equipment: The oversized heightened and widened internal storage space accommodates multiple long vertical large-format devices. A corrugated shock-absorbing sponge set comes as standard, and custom integrated slotted EVA inner liners are available. Custom cutouts tailored to the shapes of drums, instruments and lighting gear prevent sliding, friction, scratches and collisions even when rolling over bumpy terrain.
8. Weather-resistant thickened modified raw material for stable durability under extreme high and low temperatures: The material is blended with high-concentration UV-resistant and cold-resistant modified additives, maintaining stable toughness in both high and low temperature environments. It will not turn white, crack brittlely or soften and deform after long-term outdoor exposure under blazing summer sun or frigid winter conditions.
