Rolling Ruler 25cm - Parallel Ruler - Technical Drawing Ruler with Handle - Parallel Rolling Ruler - Architect Drawing Ruler - Parallel Glider Ruler Metric - Multipurpose Roller Ruler - Scale 1:1

Excellent product of qualitative materials. This ruler shows the relative angle in degrees, has a vertical ruler to 5cm and horizontal to 20cm (starting from -2 and finishing at 22), on the horizontal scale, it also starts from the middle (as 0), going both ways up to 10cm with +2cm (12cm, unmarked) on both sides. Length precision is 10 sections per cm (10 mm per 1 cm), whilst the angel precision is 10 sections per 10 degrees (1 degree precision) with 22.5, 30, 45, 60 and 90 marked distinctively, as well as every 10 degrees between 0 to 180. It also employs tiny wheels, enabling the user to draw precise parallel lines without having to adjust the ruler everytime. The wheels have plastic bands around them, preventing them from slipping on the paper, improving the precision.

Beautifully made, tracking is very accurate as it is different to my previous onean instruction set would have been useful

I am very disappointed with this product, I chose this one even though it was more expensive than similar items as I assumed it would be of better quality.I intended to use it to draw up simple building surveys as I do not have a drawing board any more and have used similar product many years ago in a drawing office.Unfortunately, the ability of this item to draw parallel lines is very poor and it only needs to be moved say 30mm away from the original line and then back again and it’s already off parallel by some margin.I will have to purchase another probably cheaper version, and throw this one away as it is effectively useless.

Small and very accurate, this high quality gadget is so well made and gives no 'slippage' on the paper as many cheaper models do. Hard to fault.

The best rolling ruler you can buy, expensive but should last a good while.

well made and accurate rolling rule. Has a quality feel about it. I needed it for calligraphy and have found it works well.

These rules are much better then the usual all plastic versions you see in the shops and altough they cost a lot more, your outlay is returned in the rules operation, less slipping greater accuracey when transfering a parrell line, ease of use and soother operation good angluar measurement could only be improved by the provistion of a good storage box. if you tried the rest now try the best

The actual rolling mechanism is very nice, and the rubber ring idea is brilliant, giving this rolling ruler a lot of traction.However, the ruler itself is horrible. Whoever designed it quite obviously did not know the first thing about ruler design.Let's start with the mechanical faults: There are no spacers to raise the ruler above the paper. The entire edge of the ruler is resting on and therefore scraping along the paper, doing damage if you are not careful, and at the very least does not allow for smooth movement. Also, since the entire edge rests on the paper, you cannot use this ruler with ink, as the ink will be sucked under the edge by the capillary effect, and smear.At this point already nearly irrelevant, but the ruler is not tapered either to reduce parallactic reading errors of the scale.

Es una regla paralex de muy buena calidad y aunque no es barata es de lo mejor que he probado en dibujos de precisión

Le cadeau a plu et sera utilisé avec plaisir, donc c'est parfait ! Merci.

This is the perfect device to manually measure anteriorlisthesis or posterlisthesis of vertebra segements suspect of sustaining ligamentous injury from various traumatic events. These events are primarily auto injuries but may also include any form of sports, military, etc injuries where symptoms last longer than the 4 weeks whereupon muscle injuries would normally be expected to heal. Dynamic Xrays are essential to arriving at a correct diagnosis when the circumstances above exist. See article by Freiheit, Diagnose Sprain Injury in MVA Cases.This is hands down the best and most useful tool of this nature for the doctor to have in his/her office to make quick determinations as to the need for MRI scans in trauma cases even when extremity symptoms fail to exit. It is extremely accurate, easy to hold and clear enough to see correctly any lithesis on plain film or digital images.Frankly, if you read xrays and treat trauma cases, this is a must have tool.

Non è che ci sia moltissimo da scrivere.... è un oggetto fatto molto bene e funziona perfettamente. Non è un giocattolo per bambini e vale quel che costa. Disegnando con l'ausilio di questo oggetto non si può avere la precisione di un tecnigrafo di alta qualità, sia chiaro, ma non nasce per questo. Lo ricomprerei sicuramente.

Genau das was ich bestellt hatte!Läst sich sehr gut paralle verschieben. Läuft leicht und ruckfre i über die Unterlage ,hat eine gute BESRIFTUNG .
