Reflective Ironwire

SKU: DXM-2020 Categories: ,


Our Reflective Ironwire is the most durable and lowest stretch reflective guyline available, making it the best possible line for your tent.

This line has a pure Dyneema® core which gives a breaking strength of 650 lbs – remarkable for a 2.0 mm line. While other Dyneema core lines exist, ours goes a step further and also weaves Dyneema into the sheath for unparalleled abrasion resistance. A pure Dyneema sheath is too slick to hold knots well and wouldn’t melt nicely to finish the ends, so our line uses a Dyneema/poly blend for the shealth to achieve the ideal balance between durability and feel.

The Dyneema and tight weave also make this line ultra low stretch, which helps your shelter stand strong during stormy conditions. Regular lines commonly stretch about 10% which allows your tent to deflect under high winds and snow loads. This line has about 1/10th as much stretch, which largely eliminates deflection for a more resolute shelter in harsh weather. We recommend this line as upgrade when camping where high winds or snow loads are a factor.

Reflective Ironwire line is built in the USA by Lawson Equipment. It is equivalent to their Ironwire cord, except we have added a 3M Scotchlite Reflective reflective tracer for night time visibility – key for a tent application.

We offer this line in 2.0 mm size, which works well with all versions of our X-Mid tents and numerous other shelters. Please note that the tight weave and low stretch materials means that this cord does not stretch thinner under load like most cords, so it performs well in cord tensioners that usually require 2.5 mm.

Q) How do you melt the ends?
A) The sheath will melt nicely to seal the cord ends. To do so, start a foot back from the cut end and squeeze your fingers along the sheath towards the end. This will work the end of the sheath past the core by 1/8″ (2-3 mm). You can then melt the sheath to seal the end.

Q) What cord tensioners does this work with?
A) The low stretch and high density of this cord means that it doesn’t stretch thinner under load like most cords. A typical 2.5 mm cord will stretch thinner to about 2.0 mm under load while our cord does not, so this 2.0 mm cord acts similar to most 2.5 mm cord in cord tensioners. Thus, it works well in almost all popular cord tensioners like LineLoc3’s and LineLoc Lite’s that we use or have used on the X-Mid and are popular on numerous other tents. If your tent works well with 2.0 – 2.5 mm line you will find this cord to be the right thickness.

Q) How much cord do I need for my X-Mid?
A) The 30′ kit is intended to be sufficient. Normally you will have two peak guylines (6-8′ ea) and then 1-2′ at each corner, so upgrading to this premium cord requires 16-24′ for the tent. Thus a 30′ kit works well for that and will have a few feet extra which you can use for extra long peak guylines, or adding side panel guyouts. Opt for our 50′ kit if you really want to outfit your X-Mid with a lot of cord (e.g. extra long corner lines, extra long peak guyouts, side panel guyouts etc) or if you plan to use it for other applications (e.g. bear bagging).
