It is ideal for use in places where a large number of unspecified people may have access, such as various facilities.

The bolt lock type floor hatch is an access panel that excels in security and safety among floor hatches. Here, we will introduce its usage scenarios and benefits. First, the bolt lock type floor hatch is ideal for use in locations where a specific large number of people may have access, such as in various facilities. For example, it may be used in public facilities and educational institutions to prevent theft and vandalism. By introducing a bolt lock type floor hatch, it can prevent unauthorized opening and closing, making it more secure and safe. Additionally, it can be locked and unlocked using a dedicated key handle, which reduces the burden on administrators. The rubber packing installed at the fitting part of the lid and frame, along with being forcibly secured by bolts, ensures high airtightness and excellent waterproof and odor-proof effects, serving to protect various equipment.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when leaving the parking lot in my car..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Departure Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel including the controller and switching power supply (24V) is required when using the departure warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
