Very visible and strong

Excellent braided line for many jobs around the house and garden. The 8 strands make it very strong but not too thick. It will stay taut if tied securely and is visible from a distance even against grass. A criss cross pattern was excellent for deterring birds from a newly sewn patch of lawn which is what I got it for. Very good line which will be useful for many things.

Strong, good value, re-useable hi-vis string-line

This bright green nylon string-line is strong, it doesn’t stretch, it’s easy to see, and just so much better than regular string, when building walls etc.It comes on a tough plastic reel, and was priced at £9.99 for 100m when reviewed. It’s re-useable, and costing just 10p a metre, it also offers good value for money.

Very useful indeed

We had two different projects going on in our garden and needed something that could mark things clearly invisibly from a distance. This high-quality nylon line fitted the bill perfectly and did the job very well indeed.The first thing you noticed is just how high-quality the string itself is. You get a full 100 m of it and because it is braided with eight strands it has a high strength tolerance and doesn't fray when cutting.We used it to mark out sizes for a potential extension and because of its bright colour it was easy to see and gave us a good idea of how to proceed. At the front of the house we needed to lay lawn seed and wanted something to deter birds from eating it. This woven in between a few sticks did the job perfectly and stayed in place for the whole time we needed it.Something very useful indeed to having your tool cupboard.

Nice mid-price 100m Masons' Line - but there's more to know

On site we have been using the W.Rose braided nylon mason's lines as the seniors all swear by it. They are the "big brand" and have been made since 1798. These rolls hold 685ft of line (just over 200m) while the special braiding process creates extra elasticity which helps eliminate any sagging, making it perfect for laying out even rows of block and brick. It is braided from 2 or 3 base colours so stand out clearly with contrasting colour patterns (which is why crafters buy it too)....But its expensive - the Aug 25 price we have been paying is Ex VAT: £27.99 andInc VAT: £33.59 -- but then it lasts for years, doesn't degrade with the alkalinity of cement and mortar and the usual UK rain!We have also tried the Rolson Brick Line. It's 100m long, has a neat plastic spool that turns into a peg for pegging out and on Amazon, costs just £4.95 (it looks a lot like the Drapers brand one that we can't seem to get anymore). On the high street it looks identical to the Screwfix 100m "Magnusson Brick Line" at £3.99. A quick look today says >1000 spools of the Rolson have been sold from UK Amazon alone (buy it off the fancy peg/spool and they sell it at £5.76 for 152m), which likely makes that the no.1 Amazon choice.So I was interested to test this £9.99 for 100m alternative to see what you get for your money Here's what I found...Pros ✅ It labelled "Heavy Duty" but it is thin at 0.4mm diameter, however is excellent to work withand I haven't broken it. Furthermore it fits nicely in the slots on our brick line runners✅ it is super stretchy so didn't sag on me (but remember it is new, and hasn't been out in the sun for long).✅ it has good visibility - green against bricks, earth or concrete stands out✅ For the price its a bit better than the cheaper Rollson/Screwfix - but that comes with the plastic spool/peg device and this is just the basic spool (but its a tough plastic spool that looks good to survive on site for a while)Cons 👉 it doesn't tie and stay as well as the W.Rose lines - so practice your Boy Scout skills to get the best out of this and stop it slipping. I needed a double knot to lock it followed by the "tightening around a nail" trick.⭐️ Durability is the key - I'll keep this under watch to see how fast the bright fluorescent colour fades and how long it remains elastic and withstands breaking.OVERALL - I like this and rate it 4**** - and would be happy to get it again as it is cost effective ....but if it gets saggy, breaks or fades inside a year of use I will be back to update my review.I gave this 4/5 because if value is what you are after - £3.99 for 100m of Magnusson Brick Line is great value that is hard to beat, while for quality there is no doubt that the W.Rose is the "Rolls Royce" brand (with the price to match).Delivery was quick - it came the next day which is great service by the store when you are in a hurry.Was this a help?

Handy to have around for many different jobs

This Grettz 100m Green Stringline is really handy! I actually got it to use as a guide for cutting my hedges nice and straight, and it's perfect for that. It's super long, has a decent thickness, and is nice and bright so it's easy to see. Great stuff!

String line

This is a descent length of string line. It is of descent quality and I like the fluorescent green colour as it's very visible. 100m should last me a while however if I happen to need more it's likely I'd order this again given the quality of the product and price.

Sturdy for string lines

Good sturdy string for string lines. Have used this recently on a decking and retaining wall project and has worked well. Was easy to unwind on the real and most important it’s strong enough so as not to break when making my lines tight.
