3-7/8 in. Hinged Bar Lock, High Security Door Guard, Diecast Zinc Construction, Satin Nickel Plated FinishThis swing bar door guard will increase peace of mind when answering the door by allowing the door to be cracked open slightly for viewing. When engaged, a ball on the keeper interlocks with the bar lock and prevents an intruder from pushing their way through. Although a standard swing bar door guard can add great security to your home, condo, apartment flat, or hotel room, there has been some concern over the wide availability of emergency release

This swing bar door guard will increase peace of mind when answering the door by allowing the door to be cracked open slightly for viewing. When engaged, a ball on the keeper interlocks with the bar lock and prevents an intruder from pushing their way through. Although a standard swing bar door guard can add great security to your home, condo, apartment/flat, or hotel room, there has been some concern over the wide availability of emergency release tools, which are meant to release swing bar door guards in cases of emergency. We have improved upon the standard door guard design and added an innovative backup thumb turn security lock that blocks the release tool from disengaging the door guard latch. In cases of emergency, hotel security or emergency crews can pop the thumb turn off of the unit by applying approximately 100 pounds of force to the door. ( note that 100 lbs. Of force is much greater than a simple kick in, so the emergency release feature does not compromise your security.) additionally, after the thumb turn lock breaks away, the unit still operates as a traditional swing bar door lock and a specially designed Anti-Lockout emergency access tool is required to swing the door guard out of place. To help prevent forced entry into your home, it is always a good idea to engage the backup thumb turn lock whenever you are not actively using your door. Defender Security by Prime-Line offers a full line of security hardware designed to protect your home and loved ones.

Grub for a good price you wont be disappointed
**Works wonderfully with Apple devices** Plugged the hub into an M2 MacBook Air and everything was recognized instantly: the 4K @ 60 Hz HDMI output displayed crisp colors, the 100 W PD pass‑through kept the laptop charged at full speed, and the SD/TF slots read cards without any lag. The same seamless experience repeated on an iPad Pro 2024, proving the hub s broad Apple compatibility. **Good flexible cables & build** The included 1 m USB‑C cable is surprisingly supple; it doesn t kink when you bend the hub around a laptop stand, and the strain‑relief sleeve prevents the connector from pulling out. The hub s aluminum body feels solid yet lightweight, and the rounded edges match Apple s design language, giving it a premium look that blends nicely on a desk. **Ethernet port performance** The Gigabit Ethernet port delivers stable, low‑latency connections even when the hub is powering the laptop at 100 W. It s a reliable fallback for Wi‑Fi‑poor environments **Overall impression** The Revodok 7‑in‑1 hub hits the sweet spot between functionality and aesthetics. It provides everything a Mac‑centric workflow needs high‑resolution HDMI, fast data ports, card readers, and robust Ethernet while looking like an extension of Apple s own product line. For anyone juggling multiple peripherals on a MacBook, iPad, or even a Steam Deck, it s a solid, hassle‑free solution.

Works perfectly aside from how hot it gets
The ability to add more ports to my different devices has been very helpful. I’ve tested it on my tablet, phone, desktop, and laptop and it’s worked exactly how I needed to. The only issue I’ve had with it is how hot it gets when using it especially when it’s using pass through charging. It will get noticeably hot when you touch it
