I have a 16-ft. "every-which-way" ladder that I've had for maybe 20
years, so when I saw what was described as a "22'" multifunction ladder
(Keller KMT-22) advertised at a considerable discount, I thought it
might be worth upgrading. BUT when I looked at the detailed specs. it
turns out that it's really only 18-ft 3-in. long: the claimed "22'" is
the height one can reach when standing on the highest permitted rung;
this, I am told, is the "industry-standard" method of labeling ladders.
I guess that if we didn't have decent regulations, we'd have 3-qt.
"gallons" of milk and gasoline, and 40-ft. reels of electrical wire
labeled as "50-ft."
I didn't buy the ladder.

I wonder what the regs are on Log Splitters. multiplying Pi R squared by the rated pump output comes up considerably less than the claimed tonnage on the one I have checked. And that is without deducting the area of the piston rod.
The rod end doesn't matter unless there is some back pressure in the
return line. Then you'd need to deduct that pressure acting on the annulus.
I don't know anything about log splitters other than those that resemble
an ax but I wonder if it's some sort of marketing concept like 'tons per
square inch exerted by the face of the wedge'.
I always understood that an extension ladder was measured by the sum of the
two lengths separately. A 22 foot ladder would be two 11 foot lengths, but
when put together for a long reach would have some overlap that reduced the
useable length to something like 18' 3". I suppose the manufacturer of a
"multifunction ladder" uses the same criteria (excuse) to compare the
ladders and to others. This would be the same as air compressor
manufacturers who boast of 5 horsepower with a motor that draws 7 amps.
After using the saw, clean up with the 5 HP shop vac. They use the
locked rotor rating that occurs for a half second or so before the
breaker trips. While meaningless by itself, if everyone uses the same
method it give you some idea for comparison.
But look here:
The "reach height" of that ladder is also 22 ft. (the same as that of
the ladder I considered buying -- and by the same manufacturer), but it
is *not* described as a 22 ft. ladder: it is described as an 18 ft.
ladder, which is its *true* height.
And here is an extension ladder from the same manufacturer:
This is described as a 16 ft. ladder, but even the "reach height" is
less than the advertised length of the ladder: only 15 ft.
When I worked for U Haul, we'd put 20 pounds into
a 20 pound tank. I asked about the 80% expansion,
and they told me that was already figured in.
The U haul near you likely provides good value,
Blue Rhino has been on the web, short filling
I have a generator that uses propane. After I had used it (after the
tornado we had in May), I took a couple of 20-pound tanks to be refilled
(not exchange). According to weight, they now hold 20 pounds each (empty
tank weight 16.6, full tank weight 36.6 pounds).
BTW, the amount they charged was similar to a Blue Rhino exchange, but
for more propane.
51 days until the winter celebration (Friday December 25, 2015 12:00:00
AM for 1 day).
I have my tanks refilled at the Ace Hardware for $14.99, and I've
watched the meter when they refill them. Usually the meter reads about
4.7 to 4.8 gallons. However, they set it on a scale while refilling, so
they go by weight, not gallons. That's still better than a Blue Rhino
Blue Rhino is charging you for convenience and I am sure they also
factor in the number of expired tanks they end up taking. I know that
is the only kind I ever swap. ;-)
Walmart just opened a new store up the street from me with Blue Rhino
swaps for $15 and the cages are full of brand new tanks. I have
already swapped 2 that were so out of test my regular guy wouldn't

Still, Blue Rhino tanks are only filled to 4 gallons. I was informed on
my last fill-up that my tank certification will have expired, so I will
be forced to exchange it next time. I'll be sure to have them check for
the newest tank they have in stock.
