Masterplug 4 Socket 13A Open Reel — Extra Sockets for Growing Spaces Without Mains Reach
Best for: Growers with larger spaces or distant equipment that needs powering from a single wall socket
Our thoughts
Limited mains outlets kill productivity. This open reel cuts through that problem cleanly — four sockets and up to 30 metres of cable length means you can power your lights, fans, controllers, and sensors without daisy-chaining leads or running extension cables all over the place. Sturdy, reliable, and built to handle the job without faffing about.
The Masterplug 4 Socket 13A Open Reel is a heavy-duty extension cable reel that solves a simple but critical problem: too few mains outlets in growing spaces. It delivers four safety-shuttered UK sockets at the end of 25–30 metres of cable, giving you genuine flexibility to position equipment where it needs to be, not where your mains socket happens to be. Built around a steel frame with a wind handle for easy retraction, it's designed for regular use in spaces where reaching from a single outlet would otherwise mean compromise.
How it compares
This sits in the professional-grade extension reel bracket for UK growing setups.
- Four sockets vs. competitors offering two or three — more flexibility per lead
- 13A capacity with integrated RCD and thermal overload protection — proper safety, not bargain-basement cutoffs
- Steel frame design stands up to daily movement and storage in workshop conditions
- Established brand with 30+ years in power distribution — you're not buying a gamble
The research shows growers specifically ask for this specification because it covers multiple pieces of equipment (lights, fans, controllers, sensors) without multiplying the number of extension leads.
Usage guidance
Power distribution in grow rooms
Plug into your main outlet, run the cable to where your equipment sits, and you've got four dedicated sockets right there. No more running five separate leads across the floor.
Equipment setup
Run your LED grow light driver, circulation fan, controller, and sensor power supplies all from one reel. Keeps the mess minimal and makes troubleshooting straightforward.
Larger spaces
25–30 metres of cable gives you genuine reach. Useful for greenhouses, polytunnels, or rooms where the socket's stuck in an awkward corner.
Cable management
The wind handle lets you reel in only what you need — no coils lying about. When fully extended, keep the cable taut to avoid tripping hazards.

- Setups where safety and proper electrical protection matter (commercial or semi-commercial operations)
- Growers who value durability and don't want to replace cheap reels every season
Best suited to anyone tired of crawling extension leads across the floor or unplugging equipment just to plug in something else.
Our take
This is straightforward kit that does one job properly — gets power where it needs to go without creating a mess or cutting corners on safety. Four sockets, 25–30 metres of reach, and proper RCD protection. No surprises, no overcomplication.
If your growing space is currently held back by mains outlet placement, worth picking up while clearance stock lasts. Masterplug are solid on longevity, so this should see you through several seasons without drama.
