Grey Dolphin Spring (Garage Door Spare Parts) to Suit Henderson Doors

It took a little while to work out the colour-coding scheme but this turned out to be a very satisfactory distress purchase after one of the existing springs broke after 40 years of service. Too mean to buy a pair, I just replaced the broken one and the door has now been troublefree for 18 months. It's straightforward to fit the new spring and adjust the tension to suit — anyone could do it, and for a fraction of the cost of most alternative solutions.

First class product and delivery. I Fitted the springs in minutes, the garage door now opens with very little effort. The original springs had been in place for over 40 years and had clearly lost their tension.

GOOD PRODUCT WHICH DOES WHAT IS EXPECTED OF IT.DELIVERY SPOT ON AND FITTED PERFECT....HAD BEEN STRUGGLING TO OPEN IT WHEN ONE SPRING BROKE . HAS TO BE A PAIR TO MAKE IT WORK RIGHT SO THIS FILLED THE BILL.

size spot on,easy to fit arrived in quick time and garage door now operational again so happy!

Needed to replace a broken garage door spring, shopped around and found this to be the best price / quality. Arrived less than 36 hours after ordering, can't fault - easy to fit too.

It's a bit short on the end loops and keeps coming adrift

Amazing fitted in minutes,garage door working as if it was a new one,could not believe the price I would recommend Amazon & Henderson to everyone .

Excellent product, feel like we have a new garage as door is so easy to open and close and first class delivery service thank you
