Nano Silk 50D 12/0 Bulk 250m Spool

Nano Silk 50D 12/0 Bulk 250m Spool is regarded as the tying thread of choice of professional fly tiers worldwide and is the best GSP thread on the market! Being so super strong and available in such a variety of colors and deniers it has endless possibilities and can be used for micro flies to large flies.

Nano Silk 50D 12/0 Bulk 250m Spool is ideal for your smaller flies and the 50d, also known as 12/0, having a wide range of colors in it, there is plenty of choice for you.

Super strong, this is the highest quality thread available. Never worry about snapping your tying thread again – you can rely on Nano Silk.

50d is also known as 12/0 is the go to GSP thread. Nano Silk 50D 12/0 Bulk 250m Spool has all the strength you would expect from this premier thread. It is 10 times stronger than steel of the same diameter! Nano Silk 50D 12/0 Bulk 250m Spool is fine enough for size 16 to 32 flies whilst still retaining its strength. Although Nano Silk 50D 12/0 Bulk 250m Spool is a fine thread it can be split down further if required so dubbing making dubbing much easier!

Nano Silk 50D 12/0 Bulk 250m Spool is designed for flies sizes 8 to 16, the ideal for most fly tiers. However do not be fooled because of Nano 50D thin diameter, Nano Silk 50D 12/0 Bulk 250m Spool is stronger than 6/0 polyester thread yet is less than 1/20th of the diameter. As a result it can be used for any fly where you do not want to see your thread.

Because Nano Silk lays perfectly flat you get no thread build up. Indeed check out our Youtube video where we put 100 wraps on a hook and still had no head buildup!

  • 12/0 50 denier thread
  • Breaking strain 1,900gm / 4.2lb
  • perfect on hook sizes 6 to 16
  • Lays perfectly flat with no build up, regardless of how many loops you put on the hook
  • 10 times stronger than steel of the same diameter

Pro Tips:
1 - rotate anti-clockwise to untwist and lay perfectly flat. With just 2 or 3 light wraps of Nano Silk over foam you can then tighten and tie in foams or materials that would cut easily.
2 – use white Nano Silk and simply color the last 4 inches (100mm) of thread for heads in a visible color

Not all GSP threads are the same as strength tests show. Nano 50D is available in black and white, with 100 meters on each spool or 50m for colored Nano 50D. We use the highest quality materials to ensure that there are no tangles and that it produces the smoothest and strongest GSP on the market in each size band. Search for Global Fly Fisher Thread Chart to see independent evidence!.

Good product, expensive price, poor adhesive
Premium packaging for a premium device. Useful for IR remote signal delivery with extra functions on the side. Price though is luxury for it’s use. Used this for a Logitech Harmony hub control of an non-smart electric fireplace. Setup is a breeze but only if you’re tech savvy. Highly recommend to watch the YouTube video for information on all it’s application. There a many other cheaper devices similar to this available on Amazon that I could have used for the same application. If you have a need for multiple control within the same vicinity of other devices, this may be more useful for you. However, if you plan on utilizing an IR repeater/extender for only a single device and would like to save some money, don’t buy this one. This device works quite well though. Have had no issues achieving the effect needed. Only four stars due to the poor adhesive on the emitter attachment. As stated earlier, I used this on an electric fireplace with a glass surface. I used the attachable emitter to the front glass sensor where the IR receiver was located on the fireplace. After only one day, the emitter attachment fell off even though I made sure the glass was thoroughly cleaned prior to adhering it. Otherwise a good product.

Denon avr ir remote port works great with sewell products
I bought a new entertainment center with glass doors and wasn't getting good signal range with the door closed. Plus i couldnt get a good of line site, since this cabinet was shorter than the orginal, and the location for my avr was further to the left than before and now my line of sight to the receiver was blocked from other parts of the room due to high couch back. I tried a couple different cheap $10 devices that used stick on transmitters/receiver buttons but they were clumsy and didn't provide me a total solution for my room layout. Works fantastic with a denon x1800 receiver (and many other models). It works directly with the denon's ir remote port in the back of the avr port. The solution is actually quite simple. Plug a stereo 3.5 mm male to male plug in the denon ir port in the back of the avr and and the other end to the orange emitter box(puck). The pics are about the size of an oreo double stuff cookie Tuck the orange box/puck away whereever and plug the power in. The box doesn't need to seen or be pointed towards anything. It's location is only limited by the length of your stereo cable and access to AC power Put the blue box puck anywhere in the room where you have general line of sight to it from where you will be using your remote, and plug power in. In my case, its sitting on top of one of my tower speakers. From there it clears the back of the couch and can see from the family room, eat-in kitchen area, and the kitchen beyond. Done. I didn't need or use any of the included emitter or transmitter cables, though if you dont have a denon, or other brand avr with an ir port to plug into , or also want to hide the blue puck ( in which case attach the included sensor cable), you'll need them. But for denon users with an ir port, you just use the two pucks and their usb power adapters. Simple.

Worked good then died at six months (Updated)
Worked good for a couple of months, then started to develop a lag between when you pressed a button on the remote, and when the TV would respond. If I moved the speaker blocking the TV’s IR receiver, and pointed the remote at it, it worked perfectly. Add the IR blaster back in and the delay returns. The delay kept getting longer and longer, sometimes 5 to 10 seconds. Then it just died. Would not pass any IR signals, even though the receiver and emitter both had power. Tried rebooting, changing communication channels to no avail. Out of Amazon return window. Manufacturer wants you do go through a troubleshooting process for warranty that is too complicated and time consuming. Customer Service Rep at Sewell send me a warranty replacement.

Nice Product and Customer Service
I ordered this BlastIR Wireless Pro IR Repeater from Sewell to replace a wired version of an IR repeater from another company. We have moved our TV on to a wall location and are in the process of hiding all the wiring out of sight behind walls and/or in a cabinet. We still have some wires to go, but this product has enabled us to eliminate the IR wiring all together. It's a real improvement in both looks and performance over the cheaper, wired version we originally tried. The BlasterIR's Receiver is the component that faces the room and receives the IR signal from our remote controls. It's small enough to fit in the space between our sound bar and the bottom of the TV. It's range is great for our room size (about 22' long and 18' wide) and picks up the remotes signal from a side angle that's almost parallel to the TV itself. The receiver is powered through one of the USB ports integrated into the TV (although the device itself supports either a USB or regular plug-in option). I haven't used them yet but Sewell appears to have provided a few options to help with affixing the IR devices in their final positions including some adhesive pads and a magnetic pad option as well. I'm still playing around with the permanent placement of the IR Blaster Emitter. It sits inside a closed cabinet and faces the concealed cable box receiver, router and DVR components. It retransmits the various IR signals it receives from the IR receiver by blasting that signal to anything it faces. I just placed it in the cabinet about 5" away from the devices I wanted to control, plugged it in and it worked with no other set up. So far the BlastIR is working seamlessly and with much better function response time than the cheaper IR version we'd tried at first. The lag time between when a button is pressed on the remote control and the action taking place on the device I'm communicating with is minimal. The emitter itself is plugged into an outlet on a surge protector powering the other in-cabinet devices, although it too could be powered via the provided USB connection if desired. As a note, we did experience a shipping issue during our ordering process. The order it self was processed quickly and shipped in a timely manner. However, there was an issue with our actual receipt of the product and the USPS who reported it delivered to our mailbox when in fact it had not been. Regardless, we reached out to Sewell directly and they quickly resolved the issue for us with no problems and in a timely manner. I would recommend both this IR Blaster Pro product as well as Sewell as a trusted company itself.

Does NOT Transmit Through Walls
Quick and easy setup! Works great within the room. However, will not work effectively between walls (i.e. - AV closet to living room).
