We’re talking stud finders today, ladies and gents, but girls, don’t get too excited. I hate to disappoint, but nothing about these babies will alert you to the top-secret, undisclosed whereabouts of Gerard Butler, Bradley Cooper or the like. While these handheld scanners will tell you exactly where the studs are, it leans much more toward the wood and metal types (you know, what your drywall is nailed to?) rather than the Hollywood variety.
Ever witnessed a “handy” person looking for studs using the old “knock along the wall until you hear a change in sound” routine? Word to the wise: never, ever, allow that joker to attempt to hang your gorgeous new Plasma screen. One’s knuckles may be a suitable stud-location system when you just want to hang a hefty picture, but when it comes to mounting a small fortune in electronics that weighs as much as a small person, think again. I don’t know your opinion on the matter, but personally, I think I could end up facing manslaughter charges if I lost a new flat screen because some well-meaning but knuckle-dependent installer missed the studs by half an inch when putting up my TV mount. A barrage of profanity from my general direction would be the least of that fool’s problems.
Lest I sound mean, let me assure you that I don’t intend to – I’m just trying to stress the importance of a accomplishing a task with a certain degree of precision – one that can only come from a high-tech gadget. When you can’t afford a mistake, spend a few extra dollars and get a tool that will guarantee success – in this case, the Greenlee Stud Sensor. Based on its readings, you’ll be able to miss studs when you need to, hit them when you need to, and avoid making contact with live AC lines at all times – all pluses in my book. Believe me: the small investment in a stud sensor is a lot less expensive than a new TV, a trip to the the hospital, or, in my hypothetical case, legal defense.
You’ve gotta love the way that garden hoses get stuck as soon as you try to move them at a weird angle. Like when you’re trying to wash your car in the driveway, and one turn too many around the vehicle stops you in your hose-toting tracks. Or when you try to drag a hose from the side yard to the backyard – get too close to the corner of the house, and snag – you’re done. Strangely enough, the same thing happens when you try to pull heavier bundled cables through cable trays.
Logistically, the whole task seems pretty straightforward, right? Just pull the darn cables from Point A to Point B. But when factors like weight, distance and the dreaded friction start playing into things, you’re bound to hit some snags – literally. What you need is something to buoy the cables up and keep them from dragging against the bottom of the cable tray. Something that will keep things rolling along smoothly without making you sweat any more than you have to. Something, hmmmmmmm…. like cable tray sheaves.
Now, why they call these things “sheaves,” I’ll never know – personally, that’s a term I’ve always associated with bundles of wheat or paper. But at this point, who cares? They just make things easier. Design-wise, cable tray sheaves are basically contoured rollers that can be temporarily mounted throughout a cable tray run to support cable bundles and keep them moving right along over long distances, as well as through bends or elevation changes. This is because they eliminate, or at least greatly cut down on, the cables’ contact with the actual tray. And in cases like this, less friction equals less exertion from you, and less potential damage to the cables. Know what else? You’ll also get the job done a lot faster.
One of the really nice things about Greenlee cable tray sheaves is that they’re reusable – as soon as you’re finished with one pull, you just pack them up and use them for the next. Installation and removal are easy – you just fasten (or unfasten) two carriage bolts and wing nuts, and you’re ready to go.
