Production will start" Polyethylene sleeve / access hole (access port) "EP-Sleeve
Polyethylene Human Passage (Human Passage Opening) EP-Sleeve ■ High Pressure Resistance: Due to its smooth double structure with a corrugated inner surface, it is strong against impacts and external pressure, possessing excellent flat strength. ■ Lightweight Material: Compared to rigid PVC pipes, it is lightweight. It enhances transportation and work efficiency, contributing to "labor-saving" at construction sites. ■ Rust Resistant: Made of high-density polyethylene, it is safe and secure for installation in water areas! ■ Cold and Chemical Resistant: Compared to rigid PVC pipes, it is suitable for installation in extremely cold regions and shows no deterioration against most chemicals. The polyethylene sleeve "accelerates the 'efficiency' of the site with its 'lightweight'!" A material that combines high pressure strength with "lightweight," which leads to direct construction usability. In particular, while rigid PVC pipes weigh about 53 kg/m, the polyethylene sleeve weighs about 17 kg/m, showcasing an overwhelming weight difference! We guarantee a definite improvement in work efficiency at construction sites. Furthermore, it also contributes to reducing the burden on workers and lowering accident risks, enhancing safety!

Notice of Functional Upgrades for Electrical Equipment CAD
We have implemented the following functional improvements in the electrical equipment CAD "MEP Designer PRO," "Brain Gear Supra," and "ARCADE NEO." 1. Wiring Length Setting In electrical equipment, when connecting wires to equipment symbols on panels, a length of 1.5M was added as excess length during the picking process. Based on requests, we have prepared a "Wiring Length Setting" command to allow for individual configuration. 2. Picking Confirmation For electrical equipment, we have improved the "Picking Confirmation" command to allow for the setting of whether or not to output excess length. Please check the attached image for details.
