Hidden Hanger

Roof-mounted hangers are usually the only option when installing gutters on a house with angled fascia or crown-molding detail on the overhangs. But roof hangers have a couple of significant drawbacks. First, the brackets are right out there in the open where they detract from an otherwise uncluttered roof. Second, they're fastened through the shingles that handle the most water. Yost Manufacturing has come up with an alternative. The Mole Hidden Hanger Attachment works with the company's standard strap hanger for roof mounting. The self-flashing mole slips under the shingles and attaches with nails. The design makes the hanger less visible and reduces the possibility of leaks.

Bigger Is Better

If you're in need of a wider composite trim board for column wraps, friezes, water tables, or arches, you might consider MiraTEC. The company's newly introduced 5/4-inch (1-inch actual) by 16-inch board joins the 4/4-inch (3/4-inch actual) by 16-inch offering introduced last year. The two boards should be a real timesaver compared to multiple pieces and glue-ups, and the 16-foot length means fewer seams than with 8-foot panel stock. According to the manufacturer, MiraTEC machines and fastens just like wood, and a zinc-borate treatment gives it greater moisture and insect resistance. MiraTEC is primed on four sides and features one smooth side and one "cedar-textured" side. It sells for about $1.40 per board foot.

Two for One

It might not be the right product for a million-dollar spec home, but for more modest projects, the Fiber Care Tub and Shower seems like a winner. The fiberglass unit includes a 5-foot or 6-foot tub and a 42-inch shower molded in one piece. The combined unit makes installation and plumbing hookups easy and practically eliminates caulk joints and owner maintenance. The shower has molded shelves and soap dishes, and the tub can be outfitted with spa jets. The 5-foot model sells for about $840 (plus shipping) and the 6-foot model sells for $100 more. A glass shower enclosure is sold separately.

On Track

A damaged patio door track can be a tough fix, and with workers carrying heavy objects in and out all day long, it's often just a matter of time before an accident happens. The FlipGard protects that vulnerable component with a sturdy temporary threshold. The yellow plastic guard mounts in front of the door, creating a small ramp to protect the track. When you want to close the door, the hinged guard flips up out of the way. It sells for about $20.

Louver Maneuver.

Louvered closet doors are a great idea. Not only do they prevent clothes from getting musty, but they also look great and give bedrooms a relaxing cabana-like feel. The only drawback is the time it takes to prime and paint all those little slats. But you can make the process go a little faster with pre-primed Miami Louver Doors from Masonite. They're available in full and half-louver designs in both passage and bi-fold models. Passage doors are available in widths from 1/0 to 3/0 and bi-fold units are available in widths from 2/0 to 6/0. All Miami Louver Doors (including bi-folds) are 1 3/8 inches thick and feature doweled joinery. The company also makes a clear pine version for staining.

Zone Defense.

Effective zoning is one of the drawbacks of forced-air heating and air-conditioning systems. If your customers are complaining that they're heating or cooling unused spaces, you might suggest the easy-to-install retrofit dampers from Arzel Technologies. Matching control panels can operate between two and eight zones using standard thermostats. The air-actuated dampers install in a diamond-shaped hole cut in the duct and have a thick foam gasket to prevent leakage. The company makes round dampers from 4 to 16 inches in diameter and rectangular models from 8 by 8 inches to 12 by 24 inches. A 6-inch round damper has a list price of $73 and their most popular two-zone control panel lists for $674.

Seal the Deal.

Sealing hvac ducts makes balancing systems easier and prevents the wasting of conditioned air inside wall cavities and chases. Most building scientists and conscientious hvac contractors agree that the best way to prevent air leakage is with duct mastic. But finding duct mastic at your lumberyard or home center is often a challenge. That might change with the introduction of Polyken and Nashua Duct Mastic from Tyco Adhesives. This industry giant might have the marketing clout to get their products more widely distributed. According to the maker, the latex product is fast drying, sag free, and resistant to mold growth. It's available in bulk tubs and 10-ounce caulking tubes.

High Style.

While working as an apprentice in my uncle's heating and refrigeration business, I remember a discussion he had with a style-conscious customer. This educated woman was totally unconcerned with the brand of her new air conditioning system, its energy efficiency, or its performance, but she insisted that the beige condenser cabinet would clash with her home's color scheme. I suspect that there are many other customers like her and at least one manufacturer has heard their cry. The York Affinity is available in six colors and features a sleek modern cabinet. It's available in sizes from 2 to 5 tons in 12 and 13 SEER ratings. I think it's a better solution than the one my uncle came up with — painting those tiny louvers was awful.

On the Job: TrussLok Screws

by Jeff Davis Like most builders today, I regularly use built-up LVL (laminated veneer lumber) beams in new construction and additions. For strength and straightness, they're unbeatable. But if there's one thing I hate, it's nailing them together. Gun nails just don't set reliably, and when you try to finish them off with a hammer, they're more likely to bend than sink in. What's more, nails don't have the ability to pull cupped LVLs tightly together. Sometimes I have to through-bolt to snug the plies together. So I was interested in checking out the new TrussLok screw (Olympic Manufacturing Group, Agawam, MA; 800/518-3569; www.fastenmaster.com), which is designed for connecting LVL, parallel-strand lumber, and laminated-strand lumber. And, as it turned out, I wasn't disappointed. The screw has a 3/8-inch hex-drive washer-head (a flared build-up under the washer reinforces the head against snapping off under torque). It's made of hardened carbon steel and has a dual coating — the red lubricating topcoat reduces driving friction and the electro-plated undercoat protects against corrosion (see Figure 1).

The screw's red coating reduces friction and helps protect the corrosion-resistant coating underneath. The manufacturer approves the screws for exterior applications with ACQ lumber.

The screws are available in three lengths for connecting various ply-combinations together. Each screw has 1 1/2 inches of thread at the end of a smooth shank to engage only a single 1 3/4-inch beam thickness which enables it to draw multiple members tightly together. But I had to check for myself the manufacturer's claim that the screw would pull a cupped LVL flat. I chose a few obviously cupped LVL cutoffs from the local lumberyard for testing.

TrussLok screws don't require predrilling and have a reinforced head to prevent snapping. The threads occupy the last 1 1/2 inches of the screw shank for drawing built-up layers tightly together.

I drove the screws using the included hex-bit and my 1/2-inch drill and found they start and drive easily. The threads are designed to be deep enough to provide good holding power, while not so deep that they generate a lot of friction as they cut through the veneer layers. I found that it's quite easy to overdrive the screw and strip out the hole. Once I realized that the screws are not meant to be countersunk, I adjusted my technique to just set the screw heads without overdriving. Projecting heads will interfere with wrapping the beam with finish lumber or drywall, but they only project 1/4 inch above the surface, so it doesn't seem like a big deal.

Drawing the cup out of the lumber took more than one screw — I drove three across the face of a 14-inch beam and tightened them progressively. Sure enough, the beams drew tightly together and the cupping disappeared. When properly installed, the drawing power is truly impressive.

The screws are rated for exterior use in ACQ-pressure-treated lumber, and come in 3 3/8-inch, 5-inch, and 6 3/4-inch lengths for various ply combinations. The .227-inch screw shanks have a posted bending yield of 160,000 psi and are claimed to provide 90% of the shear value of conventional 1/2-inch through-bolts, with no pre-drilling necessary. I know one thing for certain — I'm never going to nail another multi-ply LVL beam together.

Bags of 50 screws sell for $25 (3 3/8 inches), $29 (5 inches) and $35 (6 3/4 inches). Tubs of 250 screws sell for $89 (3 3/8 inches), $103 (5-inch) and $124 (6 3/4 inches).
