Selecting the Right Threshold Ramps for Your Needs

At HandiRamp we know that selecting the right threshold ramp can be a daunting task. There are so many different types, shapes, and sizes of ramps – how do you choose? The fastest, most convenient way to find the perfect ramp for your threshold is to start with our exclusive Threshold Ramp Configurator.  By answering a few questions, the Configurator will generate an optimized set of buying options that are based on our 60 years of helping clients find the perfect ramp.

Embedded in the Threshold Ramp Configurator is a 3-step process that you can employ on your own to find the perfect ramp. Once you’ve measured the three critical dimensions for any threshold ramp installation, these are the steps:

  1. Calculate the required length and width for the threshold ramp based on your measurements
  2. Determine the weight capacity needed for the ramp
  3. Identify whether a rubber or aluminum ramp is better suited to your needs

1. Calculate the required dimensions for the threshold ramp based on your measurements

With measurements in hand you can then go about calculating the rise, width and length of the threshold ramp required.

RAMP RISE: Some types of threshold ramps have a fixed rise height. These types of ramps include solid rubber threshold ramps, stand-alone threshold ramps, and sliding door threshold ramps.  For example, rubber threshold ramps can be ordered with a rise from ½ inch through 4 ¾ inches in half-inch increments. Aluminum stand-alone threshold ramps can be made in custom sizes, but are typically sold in 1/2″ increments starting at 3 inches. Aluminum sliding door ramps can also be made in custom sizes, and are sold in 1” increments from 1 inch to 9 inches.

Measure Height at the Top of the Threshold

Adjustable ramps can typically be raised or lowered from their standard height in minute increments. However, adjustable ramps must be ordered close to the actual rise of your threshold because their adjustability is limited, depending on the rise, from a 1/2″ to 2″.

RAMP WIDTH: Standard main doorway widths are 36″ wide, while secondary exterior doors are 32″ wide. Whether you’re looking at a rubber, aluminum, or adjustable threshold, your width choices will be 32″, 36″, or 48″. Our rubber thresholds can be trimmed to meet your specific size. Aluminum and adjustable threshold ramps cannot be trimmed. Choosing the correct width is important.

If you prefer to have a ramp that EXCEEDS the width of your door frame, the 48″ wide threshold ramp will do. Just keep in mind that you must have 48″ of space for the threshold ramp to fit in the desired location.

Since the aluminum sliding door threshold ramp functions as a 3-part kit, the width of the indoor and outdoor threshold ramps have a fixed width at 30”. The crossover bridge that connects both ramps over the sliding door tracks is available in widths of 23”, 25”, 27”, or 29”.

Measure Width of the Door Opening

RAMP LENGTH: The length of a threshold ramp (the distance from the door frame to the end of the ramp) will vary according to the ramp’s specific rise. The most common lengths are 24″, 36″, and 42″ with intermediate lengths of 8″, 10″, 12″, 16″, and 18″. Just like the width, you must have anywhere from 8″ – 42″ of length available for the threshold to fit.

2. Determine the weight capacity needed for the ramp

There are three options when choosing a weight capacity based specifically on your needs; 600lb, 750lb, or 850lb weight capacity.

When choosing your capacity, ask yourself this question: Who will be using the ramp? A mother or father utilizing a walker or wheelchair? Will someone have a stroller with them, or possibly a power scooter? If the person is in a wheelchair (non-powered) and must be pushed up, you must take into account the weight of the wheelchair, the weight of person in the wheelchair, and the weight of the person pushing them up the ramp. Having too much weight per axle could cause the ramp to buckle or crack.

3. Identify whether a rubber or aluminum ramp is better suited to your needs

ADA-compliant threshold ramps are made of either aluminum or rubber. Both types have their pros and cons and these should be examined before you make your decision.

Rubber Access Ramps Key Advantages

Cost – Recycled rubber is an inexpensive, yet extremely effective way to bridge a threshold.

Safety – Rubber ramps are naturally highly slip-resistant. Being made from recycled tires means they have some of the same gripping capabilities as a tire does to a road. However, rubber ramps are not always safe in snowy and icy conditions.

Installation – Rubber threshold ramps are easily installed, no drill needed! Furthermore, recycled rubber ramps naturally conform to uneven surfaces without modification and can easily be notched around door jams if needed.

Load Weight – Rubber ramps have a maximum capacity of 850lbs and are safe for supporting heavy equipment, furniture, and appliances.

Aluminum Access Ramps Key Advantages

Weight –  Aluminum ramps are light weight and mobile.

Safety – Handi-Ramp manufactures aluminum ramps with the same raised-button surface as our non-slip treads, ensuring that you and your family will be safe from slipping regardless of the location or weather condition.

Adjustability – Some aluminum ramps feature adjustable legs for uneven surfaces or uneven door sills, allowing the ramp to conform to any contoured surface.
