Motorola RLN4570A Break-Away Radio Chest Pack – Universal Radio Chest Harness
Part Number |
RLN4570 |
The Motorola RLN4570A Break-Away Chest Pack (also sold as the RLN4570) is a genuine Motorola universal radio chest harness. It holds your two-way radio securely on your chest, so your hands stay free during standby and the radio is always in reach. Its key safety feature is break-away tabs that release the whole pack with about 10 pounds of pull. If the harness snags on machinery, equipment or debris, it pulls away instead of trapping you. The pack fits nearly any handheld radio, including Motorola APX, MOTOTRBO XPR, XTS, CP200, HT, MTX and R7 models. It also has a built-in pen holder and a Velcro-secured pouch for small gear.
It’s a good radio chest rig for firefighters, EMS crews, search and rescue teams, industrial and plant workers, utility crews, construction and event staff.

Frequently Asked Questions
What is the Motorola RLN4570A?
The RLN4570A is Motorola’s break-away radio chest pack. It’s a universal chest harness that holds a two-way radio on your chest for hands-free carry. It has break-away tabs, a pen holder and a Velcro pouch.
How does the break-away feature work?
Break-away tabs let the whole pack pull off your body with about 10 pounds of pressure. If the harness catches on machinery, a vehicle or debris, it releases instead of holding you in place.
Will the RLN4570A fit my radio?
It fits nearly any handheld two-way radio, including APX, XPR, XTS, CP200, HT and MTX models. Motorola doesn’t approve it for the APX 4000 (454–519 MHz), the APX 6000 (383–456 MHz) or APX VHF models.
What if my waist is larger than 40 inches?
Add the 4280384F89 Black Nylon Belt Extender for extra length.
What’s the difference between the RLN4570A and the HLN6602A?
Both are universal Motorola radio chest packs with a pen holder and a Velcro pouch. The RLN4570A adds break-away safety tabs for jobs where snagging is a risk. The HLN6602A is the lower-cost standard chest pack.
Is a chest pack better than a radio strap?
A chest pack holds the radio flat and steady against your chest, which works well when you’re climbing, crawling or using both hands. A shoulder strap such as the NTN5243A lets the radio hang at your side from its carry case.
Who uses break-away radio chest packs?
Firefighters, EMS crews, search and rescue teams, industrial and plant workers, utility linemen, construction crews and event staff, especially anywhere loose straps could get caught.
