A spectacle blind or spec blind, is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service. It is different than a valve in that the blind is a permanent or long term isolation device.
One end of the blind will have an opening to allow flow through the pipe during operation and the other end is solid to block flow during maintenance

Mustâ„¢ PC1600 Charge Controllers truly represent innovation in Maximum Power Point Tracking (MPPT) technology, which enables them to increase the yield from a solar photovoltaic (PV) array as much as 30% over conventional designs. PC1600 Charge Controllers support a wide variety of system designs, battery chemistries, and integrate seamlessly in terms of system data management and programming.
The innovative PC1600 MPPT software algorithm is both continuous and active, increasing photovoltaic array power yield up to 30% compared to non-MPPT controllers. Thanks to active cooling and intelligent thermal management cooling, both PC1600 Charge Controllers can operate at their full maximum current rating, 40 AMPS or 60 AMPS respectively, in ambient temperatures as high as 113° F (45° C).
PC1600 Charge Controllers incorporate the features developed by Mustâ„¢ , including support for a wide range of nominal battery voltages and the ability to step-down a higher voltage solar array to recharge a lower voltage battery bank. A built in, backlit 70-character display shows the current status and set the key parameter at the touch of a button.

A spectacle blind is machined from a single piece of metal that is cut to match the pipe size, fit between two pipe flanges and requires an additional Gasket when it is installed. Also, the bolts will need to be lengthened depending on what piping class and size blind is used. The thickness of the spectacle blind is specified based on the line pressure and pipe size.
The specification that determines the dimensions of a spectacle blinds is ASME B16.48 - Line Blanks. A line blank conforming to this standard will be marked in the following way:
