Door Threshold / September 18, 2018 / Pauline Francoeur
Then re-assemble door system and re-shim into the indexed positions in the rough opening. At last now fasten jambs to the cinderblock with the masonry screws using shims at each screw location. Fine tune screw adjustments by wedging the shims to get the reveals around the door even. Adjust top and bottom jamb shims as necessary. Open and close door to check touching the weather stripping evenly top to bottom for any possible jambs twist. Some slight remaining jambs twist can be adjusted by persuading the jambs with a block and a hammer. Be careful. Now nail the shims permanently in position with a pneumatic nail gun shooting squarely into the cinderblock. Dont worry the nails should sink into the cinderblock as long as they are the proper length and are nailed squarely and firmly.
Buying a cheap bifold door may prove a disappointment unless you check carefully that the door you are buying will meet your needs and expectations before you order. Threshold ramps are designed to help you get over a small dip or rise. They work great for power scooters or wheelchairs as they allow you to span doorway thresholds or small steps that may otherwise would have an abrupt height gain or drop. These ramps can be fixed in place or portable. If you have an electric mobility scooter it is a good idea to have a threshold ramp. Even a 1-inch dip or rise can pose a significant barrier and could result in injury if traversed.
Most entry door thresholds are manufactured from metal or a combination of metal and wood. Metal thresholds often have black anodized coatings that are easily scratched or dented. Wood thresholds can be stained scratched and dented as well. Some manufacturers have now manufactured plastic covers to protect their exact thresholds dimensions and include the covers with the complete door unit. There are other pre-molded protectors available from online suppliers of temporary protection products. There are also a variety of tapes that can be used for threshold protection.
