What is this spare string used for?
This replacement string is designed for EK Archery Adder
crossbows running the 180lb setup. It allows you to replace a worn or damaged
string and keep your crossbow working properly.
Will this fit a standard Adder crossbow?
No — this string is made specifically for the higher tension
of the 180lb configuration. Standard Adder models require a different string.
Why does the 180lb version need a different string?
The increased draw weight puts more strain on the string, so
it must be built to handle greater tension. Using the correct string helps
maintain performance and prevents damage.
How do I know when my string needs replacing?
You should replace the string if you notice:
Fraying or worn fibres
Uneven tension
Changes in shooting consistency
Regular checks help avoid unexpected issues.
Is this ready to use straight away?
Yes, this is a complete replacement string designed to fit
compatible setups without modification.
Is it difficult to install?
Installation is generally straightforward for those familiar
with crossbow maintenance. Basic tools or stringing methods may be required
depending on your setup.
How can I make my string last longer?
To extend the lifespan:
Apply string wax regularly
Keep the rail properly lubricated
Avoid dry firing
Good maintenance helps keep performance consistent.
Should I keep a spare string?
Yes — especially with higher-powered setups, having a spare
means you won’t be stuck if your current string wears out or fails.
