For more than 20 years, America's leading companies have trusted Tripp Lite's Isobar Premium surge and noise protectors to protect sensitive computer, networking and telecom equipment. With more than 18 million satisfied customers, the Isobar remains the world's #1 selling premium surge protector. Loaded with a generous combination of high quality components, near indestructible all-metal case and unique noise filtration system, the Isobar offers the highest level of protection attainable in a multi-outlet strip. Robust surge suppression circuits with sine-wave tracking offer extreme levels of protection against the heaviest surge conditions exceeding IEEE 587 category A and B specifications and reducing 6,000V test surges to harmless levels under 35 volts. Isobar's unique protection system combines large toroidal chokes, ferrite rod-core inductors, HF/VHF capacitors and multiple layers of metal oxide varistors into exclusive isolated filter banks that remove EMI/RFI interference, even noise generated by other pieces of connected equipment. ISOBAR8ULTRA offers 8 outlets arranged in four filter banks to prevent system crashes, reboots and performance problems common as noisy system peripherals are powered off and on. Surge suppression rated at 3840 joules/97,000 amps offers network-grade protection. Widely spaced NEMA 5-15 outlets accommodate up to 4 large transformer plugs without blocking outlets. Diagnostic LEDs confirm power availability, line fault and protection status. Includes 12 foot AC line cord with space-saving angled input plug, keyhole mounting tabs and a set of 4 child safety covers.

Rated 5 out of 5 by from Built like a truck! This is my first time purchasing an Isobar, and so far, I am very impressed with the quality. This thing is built to last! I am also very happy about the fact that my devices feel very securely rooted in the outlet strip, and the plug of the device is relatively flat and plugs very securely into the wall socket. There is virtually no chance of it getting knocked out of the socket, even if you were to back a chair into it. This device cost more than I have ever paid for a power strip before, but this is no ordinary power strip!

Rated 5 out of 5 by from Will definitely be back for more as my business expands! Bought this to protect all the expensive electronics I use for my business.

Rated 5 out of 5 by from I would by another if needed. I needed a long chord to get from an outlet to my printer. I had another isobar 4-outlet surge protector that had worked very well in the past. I wanted good protection for my computer, modem, and printer. This Isobar was frosting on the cake.

Rated 5 out of 5 by from No better protection than Isobar Bought this to plug my Sony A8H 65 inch OLED TV in. I felt with a $2,000 TV I better not skimp on the surge protector. I've used the 2 port isobar before, and in my mind there is no better protection than the isobar.

Rated 5 out of 5 by from Great product! I purchased the isobar8 outlet surge protector with 12' cord to remedy what I felt was a dangerous extention cord/power strip rig that ran under my bed. It was used to power a CPAP machine, a box fan, a lamp and a phone charger. The isobar8 is a great length and has a right angle plug that sits flat on the wall, feeding the cord down and slightly off to the side so it can be plugged into the top or bottom outlet. The unit comes with outlet protectors to keep dust out of unused outlets and that's great. The unit is legit heavy duty and at 3840 joules protection I feel very safe having it in the bedroom as well as having our high priced CPAP running off of it. I will only be buying the isobar units moving forward. Safety first!

Rated 5 out of 5 by from Much needed in Florida The indicators are excellent to have. They will tell immediately if there is a problem. The housing is very sturdy. The plug on the end of the cord is flat which is nice. The best part is the $50,000 guarantee. I am in Florida and we have frequent lighting. The Isobar is an excellent protection for my Amateur Radios.

Rated 5 out of 5 by from excellect clamping voltage spec with 4 isolated filter banks An audio professional recommended this surge protector for my home theater, to protect my AVR, subwoofer, TV, PS3, Nintendo Switch, etc. His recommendation was based on two factor: clamping voltage (RMS) of 140 volts (hard to beat that spec!) and 4 isolated filter banks. Top-quality construction and plenty of space around each outlet are also beneficial, as is the touted Tripp Lite support team. So far, so good - plenty of peace-of-mind now, and protection against virtually any surge (short of a direct lightning strike!).

Rated 5 out of 5 by from It's what all the other surge supressors want to be! I purchased my 1st ISOTEL8ULTRA more than 15 years ago and it still functions perfectly after daily use. This thing is a work-horse and since I started using it I have had no surge-related equipment problems whatsoever! Since I live in a thunder-storm prone area, this is a real accomplishment. Among the features are the generous spacing of the 3-prong outlets, allowing to use cube-type transformers for small electronics and the phone-line protection. This was such a good piece of equipment, I specified it for installation at my work station, and have a second one for other equipment not located near my computer. Highly recommended!

Rated 5 out of 5 by from I would purchase this product again and again! My brother gifted me a Tripp-Lite Isobar 8-outlet surge protector and a Tripp-Lite 2-outlet direct plug in when I moved into a new apartment a few years ago. I use them for all my electronics--TV, wireless modem, landline, laptop, etc. During a few, brief outages due to severe thunderstorms over the years, the Tripp-Lite surge protectors did their job of protecting my electronics. BTW, my brother has also used these products for several years and is very happy with their performance. I recently invested in a dehumidifier and an air purifier. I want the same protection for these items and purchased another Tripp-Lite Isobar 8-outlet surge protector. I feel secure knowing my investments are protected for years to come, and additionally, are covered by Tripp-Lite's $50,000 Ultimate LIfetime Insurance.
