Door Threshold / September 17, 2018 / Martine Letourneau.
Not only do threshold ramps allow entry for scooters and wheelchairs they also help prevent tripping injuries. These ramps provide greater and safer access for all. Rubber plastic and aluminum are the most common materials used in threshold ramps. Rubber ramps are commonly sold to clear heights up to three inches. They can be used indoors or outdoors and are durable. Rubber ramps can be cut and trimmed to customize the needed height or size. They work great for door thresholds and small steps with the capability to support the weights of up to 850 pounds. Ive always enjoyed installing residential entry doors.
Theres something about thinking and working in three planes that appeals to me. Making customers happy and feeling comfortable in their home environment makes me happy too. Nothing can compare to the satisfaction of knowing a job has been well done seeing and feeling a beautiful and properly installed door operate smoothly. In modern homebuilding techniques most housing built here in the Salt Lake City area after the mid-1960s is 2x4 or 2x6 wood stick frame construction with an exterior veneer of brick stucco or some type of lap siding. Prior to that time many if not most homes around here were built using four inch wide cinderblock (4"x8"x16") masonry walls with a brick exterior veneer. Thermal efficiency properties of new door systems have improved greatly over what was available forty or fifty years ago.
During construction contractors will pass through the doorway with materials and equipment needed for the construction project. Each pass risks scratching or denting the home entryway. Temporary protection should be in place prior to the start of construction and should include protection for all the aspects of the entryway. Doors can be protected with temporary cardboard door protectors available from a variety of manufacturers. Several protectors are not only made from recycled cardboard but can be reused and recycled entirely again making these protectors truly green. The first protector to market and most popular is DoorGuard.
When youre satisfied that the door system is in the correct position drill through the thickest part of the hinge jamb with a regular drill at the hinges areas and then further drill into the cinderblock with a hammer drill. Drill the strike jamb in the same corresponding locations with the middle drilling positioned between the strike and deadbolt mortises. Countersink jambs holes to flush the masonry screw heads. It may be necessary to remove the door from the hinges for this step just remember to check the indexed jambs alignment to be sure nothing has moved. Remove shims and then remove door system from the rough opening. This must be done to install the plastic expansion sleeves into the holes drilled into the cinderblock.
