Extended Keyboard Protective Case, customizable in appearance and inner protective layers!
Integrated full-perimeter IP67 sealing for all-weather waterproof, dustproof and moistureproof performance during outdoor performances: An integrally molded high-elastic rubber sealing ring is fitted at the case opening. Once the lid is closed, the ring presses evenly against the case body all around. It blocks rainwater, sediment and moisture for open-air outdoor shows, outdoor recording on rainy days and pipeline surveys at dusty construction sites, preventing oxidation of metal keyboard ports, short circuits of circuit boards caused by dampness, and malfunctions of precision detection instruments.
Multiple integrated thickened horizontal reinforcing ribs resist compression and prevent denting and deformation: Integrated protruding horizontal reinforcing ribs run across the top and bottom of the case without weak spliced joints. The case resists denting, cracking and deformation when squeezed in backpacks or vehicles, knocked during loading and unloading, or stacked in multiple layers, offering full protection to long precision instruments during short-distance logistics transport and daily carry-around use.
Dual-sided anti-slip reinforced handles enable flexible short-distance transport across diverse scenarios: A recessed primary anti-slip handle on the front and symmetrical auxiliary side grips on both sides are all reinforced with multi-layer mechanical riveting. The case can be carried and moved from multiple angles inside narrow vehicles, backstage performance areas and stairwells, and its curved anti-slip grips avoid hand abrasion even after prolonged carrying.
Four sets of synchronized self-locking heavy-duty latches on the top with anti-theft lock holes for secure closure: Four widened and thickened spring latches are arranged on the case top. They compress the case synchronously upon closing to maintain sealing and will not pop open accidentally amid vehicle jolts or on-the-go movement. Each latch features a standard padlock hole for anti-theft locking during off-site storage and long-distance transportation.
Independent side pressure balance relief valve eliminates negative pressure resistance when opening the case across regions: The waterproof pressure relief valve automatically equalizes air pressure inside and outside the case. No negative pressure will form to suck the lid shut during intercity performances or high-altitude outdoor surveys, so the case can be opened effortlessly in different locations without forced prying.
Special flat extended inner compartment plus customizable one-piece lining for full positioning of long equipment: The slim flat extended storage compartment is custom-built for keyboards, long audio devices and pipeline detectors. A set of wavy shock-absorbing foam comes as standard, and customized one-piece slotted EVA liners are available. Separate positioning slots are cut to match the contours of long equipment, eliminating sliding, friction, scratches and bumps even when jostled while moving.
Weather-resistant modified thickened raw material ensures stable durability under high and low outdoor temperatures: UV-resistant and cold-resistant modifiers are added to the raw material to maintain stable toughness of the case in extreme temperatures. It will not turn white, crack brittlely or soften and deform after long-term exposure to intense summer sunlight or use at cold winter performance venues.

Four Sets of Symmetrical Synchronous Self-Locking Spring Latches
Wide military-grade latches are evenly distributed on the top of the case. The four latches lock synchronously to guarantee sealing performance. Standard padlock holes are pre-reserved on the latches, allowing padlocks to be installed for band tours and equipment storage at exhibitions, which can effectively prevent keyboards and precision instruments from being lost.

High-Density Thickened Wavy Shock-Absorbing Sponge for Case Lid
The optional case lid is attached with thickened high-density wavy sponge. When the case is closed, it fully wraps the internal keyboards and audio equipment. It can effectively cushion impact forces during vehicle transportation jolts and portable transit, preventing scratches and collisions on keyboard paint surfaces, keys and instrument casings.

Double-sided Multi-layer Riveted Anti-slip Reinforced Handles
Recessed anti-slip handles are installed on both the front and side panels. Multi-layer mechanical riveting enhances the overall load-bearing capacity. In confined spaces such as vehicle interiors and backstage areas where pull rods cannot be deployed, multi-angle carrying via these handles enables more flexible transportation.

4. Integral Transverse Surrounding Reinforced Rib Housing
Thickened integral transverse reinforcing ribs are formed around the entire box body to disperse impact forces generated by stacking and collisions. The lightweight box boasts outstanding compression resistance, resisting deformation and damage during daily carrying and vehicle storage.
