Frequently Asked Questions:

 

Q
Does the Fendergrip work as easy as it looks?
A

Yes. Pushing the black button drops the fender exactly where you want it. To go up, grab the Fendergrip and pull the free end of the line.

Q
How are Fendergrips sold?
A

Fendergrips are packaged and sold individually in retail marine outlets.

Q
Does the Fendergrip come with the line and fender?
A

No. Fenders and lines are manufactured and sold by other companies. You can use any available fender/line with your Fendergrips.

Q
Do I have to buy a specific model Fendergrip for my line size?
A

No. There is only one model Fendergrip which is a universal fit. We recommend 9 -13 mm line.

Q
What if my line is bigger than 13 mm?
A

First, doublecheck and measure your line size. Many boaters think in terms of their MOORING line size which is often larger. In general, pleasure boats do not need fender lines larger than 13 mm. However, if you do have larger line, your option would be to change the fender line to 13 mm double braid.

Q
Do I have to use braided line?
A

No. The Fendergrip works equally well with twisted or braided line.

Q
What holds the Fendergrip on the rail?
A

The Fendergrip is the only fender adjuster that uses the fender's line to hold itself to the boat. This makes the Fendergrip much more secure than other fender adjusters that use straps or hooks to attach to the boat.

Q
What size/shape rail can I use the Fendergrip on?
A

The Fendergrip works with any size or shape rail. It also works on cleats, stancions and many other types of fixtures.

Q
Will the Fendergrip allow the fender line to slip under a load?
A

No. the fender height will not change unless you push the button.

Q
How strong is the Fendergrip?
A

Using a 13 mm double-braided line, the Fendergrip will hold up to 262 Kg as a static load.

Q
Is my boat too small to use Fendergrips?
A

No. The beauty of the Fendergrip is that it can be used on any size boat, from small dinghys to large yachts. The smallest boat we know of using Fendergrips is a 13 foot Boston Whaler. With rails down both sides, the Whaler's owner bought the Fendergrips not only for the ease of adjustment, but more for the fender storage.

Q
Is my boat too large to use Fendergrips?
A

The largest yacht we know of using Fendergrips is a 112' Hatteras Motoryacht named "My Marilyn". Her large fenders are hole-through-the-middle (HTM) foam core fenders.

Q
How do you place the Fendergrip on the rail the very first time?
A

Pass the line up through the side opposite the black button, then over the rail. Push the button, and down through the other hole; that's it! After this first time use, the idea is to store the Fendergrip with the fender so that it's ready to use next time.

Q
I must move my fenders around; does the Fendergrip have to stay where you place it?
A

No. It is easily removed and placed elsewhere.

Q
How easy is it to reposition the Fendergrip on another part of the boat?
A

It's very easy. Push the Fendergrip's button and let the line run out of the top. Then go place it where you like, push the button, and drop the line back through the hole.

Q
What happens to the Fendergrip when you remove your fender after use?
A

The Fendergrip can be locked on top of the fender for storage. The Fendergrip can also be used to lock the fender in a fender rack when traveling in rough water.

Q
Do I need a stopper knot in the end of the fender line with the Fendergrip?
A

Yes. A stopper knot provides a physical stop for someone unfamiliar with the Fendergi. .If someone pushes and holds the release button, the stopper knot will be a failsafe to prevent the loss of a fender. On a vertical fender, a slip knot is a good choice because it can be easily undone to remove the Fendergrip. When using two Fendergrips in a horizontal storage mode, a figure-8 knot makes a good choice for a long lasting stopper knot, as the fender will be stored against a railing and not removed.

Q
How do you use two Fendergrips to store a fender?
A

Storing a fender using Fendergrips works well on a bow rail or a life-line. A hole-through-the middle fender (8" diameter or larger) with at least 12 feet of line works best. You may need more line depending on the distance of your rail, or life-line, above the water. The line should be centered on the fender with knots at both ends to prevent lateral movement. One Fendergrip is installed at each end of the fender and a figure-8 knot makes a lasting stopper knot. Both ends of the fender are then lowered for horizontal use, or one end lowered for vertical applications. Both sides are then raised for storage. The loose line can be wrapped around the fender and tucked under the rail/lifeline to keep it secure.

Q
Many boaters uses fender racks to store fenders... Why should I store a fender using Fendergrips?
A

About 40 years ago, some marine accessory manufacturers decided that the "proper" place to store fenders was up front near the bow pulpit. In practice, however, this is one of the worst places possible! The problems with fender racks are not obvious at first; they are:

  1. Blocking the Captain's forward view of the horizon. This is very dangerous when going on plane in a power boat, as well as when docking. Storing the fenders using 2 Fendergrips opens your view of the horizon and makes fenders ready to deploy.
  2. Inconvenient and cumbersome use. Fenders are NEVER used at the bow pulpit area. The fender, however, will always have to be retrieved from this area, moved, installed, and then deployed for use. This requires 4 steps. With Fendergrips, there is only one step from fender storage to deployment!
  3. Fender racks are expensive . (The cost for a pair of double stainless steel racks is significantly more than the cost of Fenderggrips.

Q
What happens to the extra line when you are storing the fender?
A

The excess line can be wrapped around the fender, and the ends tucked between the rail (or life-line) and fender. If you remember the acronym "BUT", this stands for "Behind the button", "Underneath the rail (or life-line)" and "Tuck the line". Once the fender is cinched up to the rail (or life-line), take one of the line ends and pull it behind the button, then underneath the railing (or life-line), pull the line parallel to the rail, and tuck the line between the fender and rail (or life-line). Then do the same for the other side.

Q
How many Fendergrips do I need?
A

The number of fenders on a boat depends a lot on the size of the boat, and how the fenders are to be used. We recommenf one Fendergrip for each vertical fender, and two for each fender that will be stored on a rail/lifeline.

The following is offered as a guide:

  • Power Boats up to 22 feet normally use two fenders.
  • Power Boats up to 32 feet that will use the Fendergrip Storage Feature typically use 6 Fendergrips on 4 fenders ... 4 to store two fenders, and 2 single verticals.
  • Sailboats with double lifelines typically use 8 Fendergrips ... two fenders stored on each side of the boat.
  • Large Boats ( 32-50+ feet) typically use 8-12 Fendergrips.

Q
How does the Fendergrip grab the fender line?
A

The side with the push button houses a pivoting cam that is biased by a stainless steel compression spring. The cam is coupled to the push button so that when the button is pushed, the cam releases the line. When the button is released, the spring naturally sets the line in place.

Q
Will the Fendergrip damage my fender line, or my rail?
A

No; the fender line and railing still look great after thousands of cycles!

Q
What is the Fendergrip made out of?
A

Dupont®'s Delrin®, a resin most often used for high-end marine applications.

Q
What's special about Delrin?
A

Delrin® maintains it's strength and color after being exposed to the sun and sea for years. It contains an ultraviolet (UV) inhibitor that screens out damaging sun rays. Many other fender adjusters use nylon which is cheap and weak material. It loses its strength and color with sun exposure.

Q
Are there any metal parts in the Fendergrip?
A

Yes; four 316 stainless steel screws and one 316 stainless steel compression spring.

Q
Has there ever been a spring failure?
A

No; and there are over 500,000 Fendergrips in use!

Q
How long has the Fendergrip been on the market?
A

The Fendergrip was introduced in June 1993.

Q
Are there any other products that have the Fendergrip's design?
A

No. The U.S. Patent & Trademark Office has issued two patents for the Fendergrip's unique design.

Q
I think I already have Fendergrips on my boat, or I have something just like this.
A

Do you? It's surprising how many boaters now use our brand name "Fendergrip" to refer to all fender adjusters. Although we appreciate the compliment, some other manufacturers have further confused boaters by using similar product colors, packaging, and photographs. There is only one push button fender adjuster; the Fendergrip. Compare the Fendergrip side-by-side with anything else on the market. Chances are, you will be very impressed with our product.

Q
Where is the Fendergrip made?
A

Fendergrips are made to our strict standards in Taiwan, ROC.

Q
How are Fendergrips assembled?
A

EACH Fendergrip® is carefully hand assembled, inspected, and tested for perfect operation before packaging.

Q
Is the Fendergrip buoyant?
A

No. Since the specific gravity of Delrin is 1.6, the size of the Fendergrip would have to be enormous to create an air cavity large enough to achieve buoyancy.
